Small tweaks from Ned, Mark, Cass and Steve's feedback. (#9859)
- Rename `.info` to `.column_info`.
- Rename `.select_by_type` to `.select_columns_by_type`. (to be merged into `select_columns` functionality)
- Rename `.remove_by_type` to `.remove_columns_by_type`. (to be merged into `remove_columns` functionality)
- Adding "field" `ALIAS`es.
- Making `Table.Value` private (and hence hiding `java_table`).
- Making `Column.Value` private (and hence hiding `java_column`, added method to `Storage` to allow tests to work).
- Making `DB_Table.Value` private (and hence hiding `connection`, `context` and `internal_columns`).
- Making `DB_Column.Value` private (and hence hiding `connection`, `sql_type_reference`, `expression` and `context`).
- Add widgets for everywhere `Filter_Condition` used (fix missing entry for lower, can't use auto-scoping).

# Important Notes
- Can't use `.` to access a private constructor field when mapping, have to use a lambda.
- We should agree convention for private backing fields which are wrapped by a public getter (went with `internal_` for this pass).

Refactor OrderMask to avoid memory copying (#8863)
Goal of this PR is to refactor the design of OrderMask and avoid copying arrays or lists wherever possible.
We have removed a few legacy functions which were not being used.

On a poor mans benchmark seems to be quicker (13s vs 16s) and memory usage should be lower.

Support on_problems=Problem_Behavior.Report_Warning and Map_Error wrapping in Vector.map (#8595)
Implements `Warnings.get_all wrap_errors=True` which wraps warnings attached to values inside vectors with `Map_Error`, which includes the position of the value within the vector. See [the documentation](https://github.com/enso-org/enso/blob/develop/docs/semantics/wrapped-errors.md) for more details.

`get_all wrap_errors=True` does not change the warnings that are attached to values -- it wraps them before returning them to the caller, but does not change the original warnings attached to the values.

Wrapped warnings only appear attached to the vector itself. The values inside the vector do not have their warnings wrapped.

Warning propagation is not changed at all; `Warnings.get_all` (with default `wrap_errors=False`) behaves as before. `get_all wrap_errors=True` is meant to be used primarily by the IDE, although it can be used anywhere this wrapping is desired.

3) attach extracted warnings to the result

This caused warnings to reappear when doing the custom warnings
manipulation.

Benchmark to measure startup time (#8378)
While trying to speed `MetadataStorage` up - #8324 - I felt the need to have an independent (on my computer) measurement of startup time. Here is a benchmark that measures how long execution of two simple hello world programs take.

# Important Notes
There are two benchmarks:
- `empty_startup` measures the time needed to boot without using any `Standard` library - basically _an overhead of the JVM and engine_
- `hello_world_startup` measures the use of `IO.println` - it shall take longer than `empty_startup` and show the overhead we have while processing the standard library

Upgrade enso to GraalVM for jdk 21 (#7991)
Upgrade to GraalVM JDK 21.
```
> java -version
openjdk version "21" 2023-09-19
OpenJDK Runtime Environment GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15)
OpenJDK 64-Bit Server VM GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15, mixed mode, sharing)
```

With SDKMan, download with `sdk install java 21-graalce`.

# Important Notes
- After this PR, one can theoretically run enso with any JRE with version at least 21.
- Removed `sbt bootstrap` hack and all the other build time related hacks related to the handling of GraalVM distribution.
- `project-manager` remains backward compatible - it can open older engines with runtimes. New engines now do no longer require a separate runtime to be downloaded.
- sbt does not support compilation of `module-info.java` files in mixed projects - https://github.com/sbt/sbt/issues/3368
- Which means that we can have `module-info.java` files only for Java-only projects.
- Anyway, we need just a single `module-info.class` in the resulting `runtime.jar` fat jar.
- `runtime.jar` is assembled in `runtime-with-instruments` with a custom merge strategy (`sbt-assembly` plugin). Caching is disabled for custom merge strategies, which means that re-assembly of `runtime.jar` will be more frequent.
- Engine distribution contains multiple JAR archives (modules) in `component` directory, along with `runner/runner.jar` that is hidden inside a nested directory.
- The new entry point to the engine runner is [EngineRunnerBootLoader](https://github.com/enso-org/enso/pull/7991/files#diff-9ab172d0566c18456472aeb95c4345f47e2db3965e77e29c11694d3a9333a2aa) that contains a custom ClassLoader - to make sure that everything that does not have to be loaded from a module is loaded from `runner.jar`, which is not a module.
- The new command line for launching the engine runner is in [distribution/bin/enso](https://github.com/enso-org/enso/pull/7991/files#diff-0b66983403b2c329febc7381cd23d45871d4d555ce98dd040d4d1e879c8f3725)
- [Newest version of Frgaal](https://repo1.maven.org/maven2/org/frgaal/compiler/20.0.1/) (20.0.1) does not recognize `--source 21` option, only `--source 20`.

Improve performance of Join_Condition.Between by sorting on one dimension (#8212)
- Closes #5303
- Refactors `JoinStrategy` allowing us to 'stack' join strategies on top of each other (to some extent) - currently a `HashJoin` can be followed by another join strategy (currently `SortJoin`)
- Adds benchmarks for join
- Due to limitations of the sorting approach this will still not be as fast as possible for cases where there is more than 1 `Between` condition in a single query - trying to demonstrate that in benchmarks.
- We can replace sorting by d-dimensional [RangeTrees](https://en.wikipedia.org/wiki/Range_tree) to get `O((n + m) log^d n + k)` performance (where `n` and `m` are sizes of joined tables, `d` is the amount of `Between` conditions used in the query and `k` is the result set size).
- Follow up ticket for consideration later:
#8216
- Closes #8215
- After all, it turned out that `TreeSet` was problematic (because of not enough flexibility with duplicate key handling), so the simplest solution was to immediately implement this sub-task.
- Closes #8204
- Unrelated, but I ran into this here: adds type checks to other arguments of `set`.
- Before, putting in a Column as `new_name` (i.e. mistakenly messing up the order of arguments), lead to a hard to understand `Method `if_then_else` of type Column could not be found.`, instead now it would file with type error 'expected Text got Column`.

Compare performance of Panic / Java Exception / Dataflow error (#8130)
After a discussion, I was really curious that our panics are supposed to be almost free - and while trusting that statement, it was really hard to believe - so I wanted to see for myself - knowing that an experiment is the most robust source of this kind of information - testing that in practice.

So I wrote a benchmark comparing various ways of reporting errors, also testing them both at 'shallow' and 'deep' stack traces (adding 200 additional frames) - to see how stack depth affects them, if at all.

The panics are indeed blazing fast! Kudos to the engine team. However, it seems that our dataflow errors are relatively slow (and we tend to use them _more_ than panics and want to be using them more and more). This uncovers a possible optimization opportunity. Can we make them as fast as panics??

Analysis of the benchmark results in comment below.

- Fixes missing implementations that caused `Table.union` crashing on some type pairs.
- Ensures that `Loss_Of_Integer_Precision` warning is not swallowed when numeric columns are unioned to create a `Float` column.
- Adds test for all of the above cases.
- Allow to output benchmark results to a CSV by setting an environment variable - useful for quickly comparing benchmarks, e.g. in Enso.

- Cast also exposes these types.
- The integers are still all stored as 64-bit Java `long`s, we just check their bounds. Changing underlying storage for memory efficiency may come in the future: #6109
- Fixes #7565
- Fixes #7529 by checking for arithmetic overflow in in-memory integer arithmetic operations that could overflow. Adds a documentation note saying that the behaviour for Database backends is unspecified and depends on particular database.

Invoke all Enso benchmarks via JMH (#7101)
# Important Notes
#### The Plot

- there used to be two kinds of benchmarks: in Java and in Enso
- those in Java got quite a good treatment
- there even are results updated daily: https://enso-org.github.io/engine-benchmark-results/
- the benchmarks written in Enso used to be 2nd class citizen

#### The Revelation
This PR has the potential to fix it all!
- It designs new [Bench API](88fd6fb988) ready for non-batch execution
- It allows for _single benchmark in a dedicated JVM_ execution
- It provides a simple way to wrap such an Enso benchmark as a Java benchmark
- thus the results of Enso and Java benchmarks are [now unified](https://github.com/enso-org/enso/pull/7101#discussion_r1257504440)

Long live _single benchmarking infrastructure for Java and Enso_!

Bench builder API (#7324)
Designing new `Bench` API to _collect benchmarks_ first and only execute them then. This is a minimal change to allow  implementation of #7323  - e.g. ability to invoke a _single benchmark_ via JMH harness.

# Important Notes
This is just the basic API skeleton. It can be enhanced, if the basic properties (allowing integration with JMH) are kept. It is not intent of this PR to make the API 100% perfect and usable. Neither it is goal of this PR to update existing benchmarks to use it (74ac8d7 changes only one of them to demonstrate _it all works_ somehow). It is however expected that once this PR is integrated, the newly written benchmarks (like the ones from #7270) are going to use (or even enhance) the new API.

SuggestionBuilder needs to send ascribedType of constructor parameters (#6655)
close #6611

Changelog:
- update: run compiler passes on the `ascribedType` field of the constructor arguments
- update: suggestion builder uses the type information attached to `ascribedType`
- feat: resolve qualified names in type signatures

UnresolvedSymbol is now accepted by Vector.sort (#6334)
`Vector.sort` does some custom method dispatch logic which always expected a function as `by` and `on` arguments. At the same time, `UnresolvedSymbol` is treated like a (to be resolved) `Function` and under normal circumstances there would be no difference between `_.foo` and `.foo` provided as arguments.

Rather than adding an additional phase that does some form of eta-expansion, to accomodate for this custom dispatch, this change only fixes the problem locally. We accept `Function` and `UnresolvedSymbol` and perform the resolution on the fly. Ideally, we would have a specialization on the latter but again, it would be dependent on the contents of the `Vector` so unclear if that is better.

Closes #6276,

# Important Notes
There was a suggestion to somehow modify our codegen to accomodate for this scenario but I went against it. In fact a lot of name literals have `isMethod` flag and that information is used in the passes but it should not control how (late) codegen is done. If we were to make this more generic, I would suggest maybe to add separate eta-expansion pass. But it could affect other things and could be potentially a significant change with limited potential initially, so potential future work item.

Detect conflicts between exported types and FQNs (#5986)
Exporting types named the same as the module where they are defined in `Main` modules of library components may lead to accidental name conflicts. This became apparent when trying to access `Problem_Behavior` module via a fully qualified name and the compiler rejected it. This is due to the fact that `Main` module exported `Error` type defined in `Standard.Base.Error` module, thus making it impossible to access any other submodules of `Standard.Base.Error` via a fully qualified name.

This change adds a warning to FullyQualifiedNames pass that detects any such future problems.
While only `Error` module was affected, it was widely used in the stdlib, hence the number of changes.

Closes #5902.

# Important Notes
I left out the potential conflict in micro-distribution, thus ensuring we actually detect and report the warning.

Merge ordered and unordered comparators (#5845)
Merge _ordered_ and _unordered_ comparators into a single one.

# Important Notes
Comparator is now required to have only `compare` method:
```
type Comparator
comapre : T -> T -> (Ordering|Nothing)
hash : T -> Integer
```
