Remove Array.set_at (#3634)
Implements https://www.pivotaltracker.com/story/show/182879865

# Important Notes
Note that removing `set_at` still does not make our arrays fully immutable - `Array.copy` can still be used to mutate them.

Builtin Date_Time, Time_Of_Day, Zone (#3658)
* Builtin Date_Time, Time_Of_Day, Zone

Improved polyglot support for Date_Time (formerly Time), Time_Of_Day and
Zone. This follows the pattern introduced for Enso Date.

Minor caveat - in tests for Date, had to bend a lot for JS Date to pass.
This is because JS Date is not really only a Date, but also a Time and
Timezone, previously we just didn't consider the latter.
Also, JS Date does not deal well with setting timezones so the trick I
used is to first call foreign function returning a polyglot JS Date,
which is converted to ZonedDateTime and only then set the correct
timezone. That way none of the existing tests had to be changes or
special cased.

Additionally, JS deals with milliseconds rather than nanoseconds so
there is loss in precision, as noted in Time_Spec.

* Add tests for Java's LocalTime

* changelog

* Make date formatters in table happy

* PR review, add more tests for zone

* More tests and fixed a bug in column reader

Column reader didn't take into account timezone but that was a mistake
since then it wouldn't map to Enso's Date_Time.
Added tests that check it now.

* remove redundant conversion

* Update distribution/lib/Standard/Base/0.0.0-dev/src/Data/Time.enso

Co-authored-by: Radosław Waśko <radoslaw.wasko@enso.org>

* First round of addressing PR review

* don't leak java exceptions in Zone

* Move Date_Time to top-level module

* PR review

Use Vector.from_polyglot_array to make Vectors backed by polyglot arrays (#3628)
Use Proxy_Polyglot_Array as a proxy for polyglot arrays, thus unifying
the way the underlying array is accessed in Vector.

Used the opportunity to cleanup builtin lookup, which now actually
respects what is defined in the body of @Builtin_Method annotation.

Also discovered that polyglot null values (in JS, Python and R) were leaking to Enso.
Fixed that by doing explicit translation to `Nothing`.

Tidy up the default imports for Standard.Table (#3660)
- Removed various unnecessary `Standard.Base` imports still left behind.
- Added `Regex` to default `Standard.Base`.
- Removed aliasing from the examples as no longer needed (case coercion no long occurs).
- Remove `import Standard.Table` from within the Table library (directly importing types).
- Reviewed what was in `Standard.Database` - a few tweaks and removals.
- Removed various un-needed aliasing following Hubert's import work.

Support module imports using a qualified name (#3608)
This change allows for importing modules using a qualified name and deals with any conflicts on the way.
Given a module C defined at `A/B/C.enso` with
```
type C
type C a
```
it is now possible to import it as
```
import project.A
...
val x = A.B.C 10
```

Given a module located at `A/B/C/D.enso`, we will generate
intermediate, synthetic, modules that only import and export the successor module along the path.
For example, the contents of a synthetic module B will look like
```
import <namespace>.<pkg-name>.A.B.C
export <namespace>.<pkg-name>.A.B.C
```
If module B is defined already by the developer, the compiler will _inject_ the above statements to the IR.

Also removed the last elements of some lowercase name resolution that managed to survive recent
changes (`Meta.Enso_Project` would now be ambiguous with `enso_project` method).

Finally, added a pass that detects shadowing of the synthetic module by the type defined along the path.
We print a warning in such a situation.

Related to https://www.pivotaltracker.com/n/projects/2539304

# Important Notes
There was an additional request to fix the annoying problem with `from` imports that would always bring
the module into the scope. The changes in stdlib demonstrate how it is now possible to avoid the workaround of
```
from X.Y.Z as Z_Module import A, B
```
(i.e. `as Z_Module` part is almost always unnecessary).

Explicit self (#3569)
This change modifies the current language by requiring explicit `self` parameter declaration
for methods. Methods without `self` parameter in the first position should be treated as statics
although that is not yet part of this PR. We add an implicit self to all methods
This obviously required updating the whole stdlib and its components, tests etc but the change
is pretty straightforward in the diff.

Notice that this change **does not** change method dispatch, which was removed in the last changes.
This was done on purpose to simplify the implementation for now. We will likely still remove all
those implicit selfs to bring true statics.
Minor caveat - since `main` doesn't actually need self, already removed that which simplified
a lot of code.

Improved polyglot Date support (#3559)
Significantly improves the polyglot Date support (as introduced by #3374). It enhances the `Date_Spec` to run it in four flavors:
- with Enso Date (as of now)
- with JavaScript Date
- with JavaScript Date wrapped in (JavaScript) array
- with Java LocalDate allocated directly

The code is then improved by necessary modifications to make the `Date_Spec` pass.

# Important Notes
James has requested in [#181755990](https://www.pivotaltracker.com/n/projects/2539304/stories/181755990) - e.g. _Review and improve InMemory Table support for Dates, Times, DateTimes, BigIntegers_ the following program to work:
```
foreign js dateArr = """
return [1, new Date(), 7]

main =
IO.println <| (dateArr.at 1).week_of_year
```
the program works with here in provided changes and prints `27` as of today.

@jdunkerley has provided tests for proper behavior of date in `Table` and `Column`. Those tests are working as of [f16d07e](f16d07e640). One just needs to accept `List<Value>` and then query `Value` for `isDate()` when needed.

Last round of changes is related to **exception handling**. 8b686b12bd makes sure `makePolyglotError` accepts only polyglot values. Then it wraps plain Java exceptions into `WrapPlainException` with `has_type` method - 60da5e70ed - the remaining changes in the PR are only trying to get all tests working in the new setup.

The support for `Time` isn't part of this PR yet.

Implementing basic functions (#3554)
The language specification suggests to add [five basic functions into the standard library](https://github.com/enso-org/design/blob/wip/wd/enso-spec/epics/enso-spec-1.0/05.%20Functions.md#useful-functions-in-the-standard-library). `identity`, `flip`, `const`, `curry` & `uncurry`.

# Important Notes
The new functions are being added into existing `Function.enso` file. That may not be the best place, but it is not clear from the [design spec](https://github.com/enso-org/design/blob/wip/wd/enso-spec/epics/enso-spec-1.0/05.%20Functions.md#useful-functions-in-the-standard-library) how they are supposed to be imported. I can move them wherever needed.

There is a documentation provided for each of the functions, but I am not sure how to verify it is correct. Do we generate the documentation for stdlib somehow?

Allow filtering caught error type in Error.catch (#3574)
More and more often I need a way to only recover a specific type of a dataflow error (in a similar manner as with panics). So the API for `Error.catch` has been amended to more closely resemble `Panic.catch`, allowing to handle only specific types of dataflow errors, passing others through unchanged. The default is `Any`, meaning all errors are caught by default, and the behaviour of `x.catch` remains unchanged.

Remove 'here' and make method name resolution case-sensitive (#3538)
Modified UppercaseNames to now resolve methods without an explicit `here` to point to the current module.
`here` was also often used instead of `self` which was allowed by the compiler.
Therefore UppercaseNames pass is now GlobalNames and does some extra work -
it translated method calls without an explicit target into proper applications.

# Important Notes
There was a long-standing bug in scopes usage when compiling standalone expressions.
This resulted in AliasAnalysis generating incorrect graphs and manifested itself only in unit tests
and when running `eval`, thus being a bit hard to locate.
See `runExpression` for details.

Additionally, method name resolution is now case-sensitive.

Obsolete passes like UndefinedVariables and ModuleThisToHere were removed. All tests have been adapted.

Towards a full-blown builtins DSL (part 3) (#3471)
Auto-generate all builtin methods for builtin `File` type from method signatures.
Similarly, for `ManagedResource` and `Warning`.
Additionally, support for specializations for overloaded and non-overloaded methods is added.
Coverage can be tracked by the number of hard-coded builtin classes that are now deleted.

## Important notes

Notice how `type File` now lacks `prim_file` field and we were able to get rid off all of those
propagating method calls without writing a single builtin node class.
Similarly `ManagedResource` and `Warning` are now builtins and `Prim_Warnings` stub is now gone.

Move Builtin Types and Methods to stdlib (#3363)
This PR replaces hard-coded `@Builtin_Method` and `@Builtin_Type` nodes in Builtins with an automated solution
that a) collects metadata from such annotations b) generates `BuiltinTypes` c) registers builtin methods with corresponding
constructors.
The main differences are:
1) The owner of the builtin method does not necessarily have to be a builtin type
2) You can now mix regular methods and builtin ones in stdlib 
3) No need to keep track of builtin methods and types in various places and register them by hand (a source of many typos or omissions as it found during the process of this PR)

Related to #181497846
Benchmarks also execute within the margin of error.

### Important Notes

The PR got a bit large over time as I was moving various builtin types and finding various corner cases.
Most of the changes however are rather simple c&p from Builtins.enso to the corresponding stdlib module.
Here is the list of the most crucial updates:
- `engine/runtime/src/main/java/org/enso/interpreter/runtime/builtin/Builtins.java` - the core of the changes. We no longer register individual builtin constructors and their methods by hand. Instead, the information about those is read from 2 metadata files generated by annotation processors. When the builtin method is encountered in stdlib, we do not ignore the method. Instead we lookup it up in the list of registered functions (see `getBuiltinFunction` and `IrToTruffle`)
- `engine/runtime/src/main/java/org/enso/interpreter/runtime/callable/atom/AtomConstructor.java` has now information whether it corresponds to the builtin type or not.
- `engine/runtime/src/main/scala/org/enso/compiler/codegen/RuntimeStubsGenerator.scala` - when runtime stubs generator encounters a builtin type, based on the @Builtin_Type annotation, it looks up an existing constructor for it and registers it in the provided scope, rather than creating a new one. The scope of the constructor is also changed to the one coming from stdlib, while ensuring that synthetic methods (for fields) also get assigned correctly
- `engine/runtime/src/main/scala/org/enso/compiler/codegen/IrToTruffle.scala` - when a builtin method is encountered in stdlib we don't generate a new function node for it, instead we look it up in the list of registered builtin methods. Note that Integer and Number present a bit of a challenge because they list a whole bunch of methods that don't have a corresponding method (instead delegating to small/big integer implementations).
During the translation new atom constructors get initialized but we don't want to do it for builtins which have gone through the process earlier, hence the exception
- `lib/scala/interpreter-dsl/src/main/java/org/enso/interpreter/dsl/MethodProcessor.java` - @Builtin_Method processor not only  generates the actual code fpr nodes but also collects and writes the info about them (name, class, params) to a metadata file that is read during builtins initialization 
- `lib/scala/interpreter-dsl/src/main/java/org/enso/interpreter/dsl/MethodProcessor.java` - @Builtin_Method processor no longer generates only (root) nodes but also collects and writes the info about them (name, class, params) to a metadata file that is read during builtins initialization
- `lib/scala/interpreter-dsl/src/main/java/org/enso/interpreter/dsl/TypeProcessor.java` - Similar to MethodProcessor but handles @Builtin_Type annotations. It doesn't, **yet**, generate any builtin objects.  It also collects the names, as present in stdlib, if any, so that we can generate the names automatically (see generated `types/ConstantsGen.java`)
- `engine/runtime/src/main/java/org/enso/interpreter/node/expression/builtin` - various classes annotated with @BuiltinType to ensure that the atom constructor is always properly registered for the builitn. Note that in order to support types fields in those, annotation takes optional `params` parameter (comma separated). 
- `engine/runtime/src/bench/scala/org/enso/interpreter/bench/fixtures/semantic/AtomFixtures.scala` - drop manual creation of test list which seemed to be a relict of the old design

Extend Aggregate_Spec test suite with tests for missed edge-cases to ensure the feature is well-tested on all backends (#3383)
Implements https://www.pivotaltracker.com/story/show/181805693 and finishes the basic set of features of the Aggregate component.

Still not all aggregations are supported everywhere, because for example SQLite has quite limited support for aggregations. Currently the workaround is to bring the table into memory (if possible) and perform the computation locally. Later on, we may add more complex generator features to emulate the missing aggregations with complex sub-queries.

Data analysts should be able to reverse strings using Text.reverse (#3377)
This commit implements `Text.reverse` as an extension on `Text`.
`Text.reverse` reverses strings. For example: `"Hello World!".reverse`
results in `"!dlroW olleH"`.

Strings are reversed by their Extended Grapheme Clusters not by their
characters. This has some performance implications because we need to
find these grapheme cluster boundaries when iterating. To do so,
`BreakIterator.getCharacterInstance` is used.

Within Vector, use Array.Copy wherever possible (#3236)
Following the Slice and Array.Copy experiment, took just the Array.Copy parts out and built into the Vector class.

This gives big performance wins in common operations:

| Test | Ref | New |
| --- | --- | --- |
| New Vector | 41.5 | 41.4 |
| Append Single | 26.6 | 4.2 |
| Append Large | 26.6 | 4.2 |
| Sum | 230.1 | 99.1 |
| Drop First 20 and Sum | 343.5 | 96.9 |
| Drop Last 20 and Sum | 311.7 | 96.9 |
| Filter | 240.2 | 92.5 |
| Filter With Index | 364.9 | 237.2 |
| Partition | 772.6 | 280.4 |
| Partition With Index | 912.3 | 427.9 |
| Each | 110.2 | 113.3 |

*Benchmarks run on an AWS EC2 r5a.xlarge with 1,000,000 item count, 100  iteration size run 10 times.*

# Important Notes
Have generally tried to push the `@Tail_Call` down from the Vector class and move to calling functions on the range class.

- Expanded benchmarks on Vector
- Added `take` method to Vector
- Added `each_with_index` method to Vector
- Added `filter_with_index` method to Vector
