Integer.parse and Decimal.parse improvements (#3934)
Converting `Integer.parse` into a builtin and making sure it can parse big values like `100!`. Adding `locale` parameter to `Locale.parse` and making sure it parses `32,5` as `32.5` double in Czech locale.

Import modules' extension methods only with unqualified import statements (#3906)
# Important Notes
Note that one cannot
```
import Standard.Table as Table_Module
```
because of the 2-component name restriction that gets desugared to `Standard.Table.Main` and we have to write
```
import Standard.Table.Main as Table_Module
```
in a few places. Once we move `Json.to_table` extension this can be improved.

Enhanced Vector Builder (#3809)
Manual implementation of vector builder that avoid any copying (if the initial `capacity` is exact). Moreover the builder optimizes for  storage of `double` and `long` values - if the array homogeneously consists of these values, then no boxing happens and only primitive types are stored.

# Important Notes
Added few tests to [Vector_Spec.enso](76d2f38247).

Tidy Standard.Base part 4 of n ... (#3898)
- Export all for `Problem_Behavior` (allowing for Report_Warning, Report_Error and Ignore to be trivially used).
- Renamed `Range.Range_Data` to `Range.Value` moved to using `up_to` wherever possible.
- Reviewed `Function`, `IO`, `Polyglot`, `Random`, `Runtime`, `System`.
- `File` now published as type. Some static methods moved to `Data` others into type. Removed `read_bytes` static.
- New `Data` module for reading input data in one place (e.g. `Data.read_file`) will add `Data.connect` later.
- Added `Random` module to the exports.
- Move static methods into `Warning` type and exporting the type not the module.

# Important Notes
- Sorted a few imports into order (ordering by direct import in project, then by from import in project then polyglot and finally self imports).

Upgrade to GraalVM 22.3.0 (#3663)
Upgrading to GraalVM 22.3.0.

# Important Notes
- Removed all deprecated `FrameSlot`, and replaced them with frame indexes - integers.
- Add more information to `AliasAnalysis` so that it also gathers these indexes.
- Add quick build mode option to `native-image` as default for non-release builds
- `graaljs` and `native-image` should now be downloaded via `gu` automatically, as dependencies.
- Remove `engine-runner-native` project - native image is now build straight from `engine-runner`.
- We used to have `engine-runner-native` without `sqldf` in classpath as a workaround for an internal native image bug.
- Fixed chrome inspector integration, such that it shows values of local variables both for current stack frame and caller stack frames.
- There are still many issues with the debugging in general, for example, when there is a polyglot value among local variables, a `NullPointerException` is thrown and no values are displayed.
- Removed some deprecated `native-image` options
- Remove some deprecated Truffle API method calls.

Tidy Standard.Base part 3 of n ... (#3893)
Here we go again...
- Tidied up `Pair` and stopped exporting `Pair_Data`. Adjusted so type exported.
- Tidy imports for `Json`, `Json.Internal`, `Locale`.
- Tidy imports Ordering.*. Export `Sort_Direction` and `Case_Sensitivity` as types.

- Tidied the `Regression` module.
- Move methods of `Date`, `Date_Time`, `Duration`, `Time_Of_Day` and `Time_Zone` into type. Publishing types not modules.
- Added exporting `Period`, `Date_Period` and `Time_Period` as types. Static methods moved into types.

# Important Notes
- Move `compare_to_ignore_case`, `equals_ignore_case` and `to_case_insensitive_key` from Extensions into `Text`.
- Hiding polyglot java imports from export all in `Main.enso`.

Some minor fixes (#3874)
- Allow `Map` to store a `Nothing` key (fixes `Vector.distinct` with a `Nothing`).
- Add `column_names` method to `Table` as a shorthand.
- Return data flow error when comparing with Nothing (not a Panic or a Polyglot exception).
- Allow milli and micro second for DateTime and Time Of Day

# Important Notes
- Added a load of tests for the various comparison operators to Numbers_Spec.

Don't add module's builtins to the scope of a builtin type (#3791)
It appears that we were always adding builtin methods to the scope of the module and the builtin type that shared the same name.
This resulted in some methods being accidentally available even though they shouldn't.

This change treats differently builtins of types and modules and introduces auto-registration feature for builtins.
By default all builtin methods are registered with a type, unless explicitly defined in the annotation property.
Builtin methods that are auto-registered do not have to be explicitly defined and are registered with the underlying type.
Registration correctly infers the right type, depending whether we deal with static or instance methods.

Builtin methods that are not auto-registered have to be explicitly defined **always**. Modules' builtin methods are the prime example.

# Important Notes
Builtins now carry information whether they are static or not (inferred from the lack of `self` parameter).
They also carry a `autoRegister` property to determine if a builtin method should be automatically registered with the type.

Parse the standard library (#3830)
Fix bugs in `TreeToIr` (rewrite) and parser. Implement more undocumented features in parser. Emulate some old parser bugs and quirks for compatibility.

Changes in libs:
- Fix some bugs.
- Clean up some odd syntaxes that the old parser translates idiosyncratically.
- Constructors are now required to precede methods.

# Important Notes
Out of 221 files:
- 215 match the old parser
- 6 contain complex types the old parser is known not to handle correctly

So, compared to the old parser, the new parser parses 103% of files correctly.

Add Period type (#3818)
This PR adds `Period` type, which is a date-only complement to `Duration` builtin type.

# Important Notes
- `Period` replaces `Date_Period`, and `Time_Period`.
- Added shorthand constructors for `Duration` and `Period`. For example: `Period.days 10` instead of `Period.new days=10`.
- `Period` can be compared to other `Period` in some cases, other cases throw an error.

# Important Notes
- Some (Gregorian) calendar related functionalities within `Date` and `Date_Time` now produces a warning  if the receiving Date/Date_Time is before the epoch start, e.g., `week_of_year`, `is_leap_year`, etc.

State rework & IO Contexts (#3828)
1. Changes how we do monadic state – rather than a haskelly solution, we now have an implicit env with mutable data inside. It's better for the JVM. It also opens the possibility to have state ratained on exceptions (previously not possible) – both can now be implemented.
2. Introduces permission check system for IO actions.

Accept Array-like objects seamlessly in builtins (#3817)
Most of the time, rather than defining the type of the parameter of the builtin, we want to accept every Array-like object i.e. Vector, Array, polyglot Array etc.
Rather than writing all possible combinations, and likely causing bugs on the way anyway as we already saw, one should use `CoerceArrayNode` to convert to Java's `Object[]`.
Added various test cases to illustrate the problem.

Move logic calculating the index in Vector.at to a builtin method to make the performance of Vector to be on par with Array (#3811)
The main culprit of a Vector slowdown (when compared to Array) was the normalization of the index when accessing the elements. Turns out that the Graal was very persistent on **not** inlining that particular fragment and that was degrading the results in benchmarks.

Being unable to force it to do it (looks like a combination of thunk execution and another layer of indirection) we resorted to just moving the normalization to the builtin method. That makes Array and Vector perform roughly the same.

Moved all handling of invalid index into the builtin as well, simplifying the Enso implementation. This also meant that `Vector.unsafe_at` is now obsolete.
Additionally, added support for negative indices in Array, to behave in the same way as for Vector.

# Important Notes
Note that this workaround only addresses this particular perf issue. I'm pretty sure we will have more of such scenarios.
Before the change `averageOverVector` benchmark averaged around `0.033 ms/op` now it does consistently `0.016 ms/op`, similarly to `averageOverArray`.

- Allow Enso method dispatch on `Duration` interop coming from different languages.

# Important Notes

By-type pattern matching (#3742)
This change brings by-type pattern matching to Enso.
One can pattern match on Enso types as well as on polyglot types.

For example,
```
case x of
_ : Integer -> ...
_ : Text -> ...
_ -> ...
```
as well as Java's types
```
case y of
_ : ArrayList -> ...
_ : List -> ...
_ : AbstractList -> ...
_ -> ..
```

It is no longer possible to match a value with a corresponding type constructor.
For example
```
case Date.now of
Date -> ...
```
will no longer match and one should match on the type (`_ : Date`) instead.
```
case Date of
Date -> ...
```
is fine though, as requested in the ticket.

The change required further changes to `type_of` logic which wasn't dealing well with polyglot values.

Implements https://www.pivotaltracker.com/story/show/183188846

# Important Notes
~I discovered late in the game that nested patterns involving type patterns, such as `Const (f : Foo) tail -> ...` are not possible due to the old parser logic.
I would prefer to add it in a separate PR because this one is already getting quite large.~ This is now supported!

Implement type_of (#3722)
This change implements a simple `type_of` method that returns a type of a given value, including for polyglot objects.

The change also allows for pattern matching on various time-related instances. It is a nice-to-have on its own, but it was primarily needed here to write some tests. For equality checks on types we currently can't use `==` due to a known _feature_ which essentially does wrong dispatching. This will be improved in the upcoming statics PR so we agreed that there is no point in duplicating that work and we can replace it later.

Also, note that this PR changes `Meta.is_same_object`. Comparing types revealed that it was wrong when comparing polyglot wrappers over the same value.

Don't rename imported Main module that only imports names (#3710)
Turns that if you import a two-part import we had special code that would a) add Main submodule b) add an explicit rename.

b) is problematic because sometimes we only want to import specific names.
E.g.,
```
from Bar.Foo import Bar, Baz
```
would be translated to
```
from Bar.Foo.Main as Foo import Bar, Baz
```
and it should only be translated to
```
from Bar.Foo.Main import Bar, Baz
```

This change detects this scenario and does not add renames in that case.

- All `File_Format` types now have a `can_read` method to decide if they can read a file.
- Move `Standard.Table.IO.File_Format.Text.Text_Data` to `Standard.Base.System.File_Format.Plain_Text_Format.Plain_Text`.
- Move `Standard.Table.IO.File_Format.Bytes` to `Standard.Base.System.File_Format.Bytes`.
- Move `Standard.Table.IO.File_Format.Infer` to `Standard.Base.System.File_Format.Infer`. **(doesn't belong here...)**
- Move `Standard.Table.IO.File_Format.Unsupported_File_Type` to `Standard.Base.Error.Common.Unsupported_File_Type`.
- Add `Infer`, `File_Format`, `Bytes`, `Plain_Text`, `Plain_Text_Format` to `Standard.Base` exports.
- Fold extension methods of `Standard.Base.Meta.Unresolved_Symbol` into type.
- Move `Standard.Table.IO.File_Format.Auto` to `Standard.Table.IO.Auto_Detect.Auto_Detect`.
- Added a `types` Vector of all the built in formats.
- `Auto_Detect` asks each type if they `can_read` a file.
- Broke up and moved `Standard.Table.IO.Excel` into `Standard.Table.Excel`:
- Moved `Standard.Table.IO.File_Format.Excel.Excel_Data` to `Standard.Table.Excel.Excel_Format.Excel_Format.Excel`.
- Renamed `Sheet` to `Worksheet`.
- Internal types `Reader` and `Writer` providing the actual read and write methods.
- Created `Standard.Table.Delimited` with similar structure to `Standard.Table.Excel`:
- Moved `Standard.Table.IO.File_Format.Delimited.Delimited_Data` to `Standard.Table.Delimited.Delimited_Format.Delimited_Format.Delimited`.
- Moved `Standard.Table.IO.Quote_Style` to `Standard.Table.Delimited.Quote_Style`.
- Moved the `Reader` and `Writer` internal types into here. Renamed methods to have unique names.
- Add `Aggregate_Column`, `Auto_Detect`, `Delimited`, `Delimited_Format`, `Excel`, `Excel_Format`, `Sheet_Names`, `Range_Names`, `Worksheet` and `Cell_Range` to `Standard.Table` exports.

Improved Vector/Array interop (#3667)
`Vector` type is now a builtin type. This requires a bunch of additional builtin methods for its creation:
- Use `Vector.from_array` to convert any array-like structure into a `Vector` [by copy](f628b28f5f)
- Use (already existing) `Vector.from_polyglot_array` to convert any array-like structure into a `Vector` **without** copying
- Use (already existing) `Vector.fill 1 item` to create a singleton `Vector`

Additional, for pattern matching purposes, we had to implement a `VectorBranchNode`. Use following to match on `x` being an instance of `Vector` type:
```
import Standard.Base.Data.Vector

size = case x of
Vector.Vector -> x.length
_ -> 0
```

Finally, `VectorLiterals` pass that transforms `[1,2,3]` to (roughly)
```
a1 = 1
a2 = 2
a3 = 3
Vector (Array (a1,a2, a3))
```
had to be modified to generate
```
a1 = 1
a2 = 2
a3 = 3
Vector.from_array (Array (a1, a2, a3))
```
instead to accomodate to the API changes. As of 025acaa676 all the known CI checks passes. Let's start the review.

# Important Notes
Matching in `case` statement is currently done via `Vector_Data`. Use:
```
case x of
Vector.Vector_Data -> True
```
until a better alternative is found.

Get rid of free-floating atoms. Everything has a type now! (#3671)
This is a step towards the new language spec. The `type` keyword now means something. So we now have
```
type Maybe a
Some (from_some : a)
None
```
as a thing one may write. Also `Some` and `None` are not standalone types now – only `Maybe` is.
This halfway to static methods – we still allow for things like `Number + Number` for backwards compatibility. It will disappear in the next PR.

The concept of a type is now used for method dispatch – with great impact on interpreter code density.

Some APIs in the STDLIB may require re-thinking. I take this is going to be up to the libraries team – some choices are not as good with a semantically different language. I've strived to update stdlib with minimal changes – to make sure it still works as it did.

It is worth mentioning the conflicting constructor name convention I've used: if `Foo` only has one constructor, previously named `Foo`, we now have:
```
type Foo
Foo_Data f1 f2 f3
```

This is now necessary, because we still don't have proper statics. When they arrive, this can be changed (quite easily, with SED) to use them, and figure out the actual convention then.

I have also reworked large parts of the builtins system, because it did not work at all with the new concepts.

It also exposes the type variants in SuggestionBuilder, that was the original tiny PR this was based on.

PS I'm so sorry for the size of this. No idea how this could have been smaller. It's a breaking language change after all.
