Collects files from `package:async_helper` and `tests/language`
that are generally useful, so that all test-related helpers are
in `package:expect`.
Moves the two libraries from `package:async_helper` into `package:expect`,
and the `tests/language/static_type_helper.dart` file too.
Deprecates `async_minitest.dart`, to follow `minitest.dart`,
expecting the Flutter use of it to have been fixed to not break
on deprecation (I believe Flutter no longer breaks builds on deprecations at all).
Patch 1 is the actual change.
Patch 2+4+8 is changing all existing references to the files.
Patch 6 ignores deprecation in files still using `async_minitest.dart`.
3+5+7+9 are updating this text to make the numbers match.
Then it's just test-expectations and small tweaks from there.

This is a reland of commit d84f908641
Includes fixes:
--- Catch scope fix ---
Each catch block should define its own scope, but the compiler was not treating the body of these catch blocks as a scope. This was leading to incorrect variable renaming.
--- Duplicate label fix ---
Labels weren't being removed from the _labelNames Map after being used so multiple nodes were getting tagged with the same label. Note: This didn't actually cause any bugs because the label closer to the break statements using those labels was the correct one.
--- addAsyncCallback cleanup ---
The new async semantics actually don't require managing addAsyncCallback and removeAsyncCallback calls (proxies for async_helper.asyncStart and async_helper.asyncEnd). None of the other backends manage these themselves. It's up to tests to ensure they call async_helper.asyncStart and async_helper.asyncEnd.

Also require a `List` in places where an `Iterable`
wasn't necessary.
* Avoid doing complicated computations that are also

This reduce the memory footprint and cost of parsing these extensions. Another
advantage is a reduction on the size of the .map files. On a large customer
app, this was a 11% reduction, and the frames section was about 1Mb (excluding
the extra names and uris added on the existing tables).
The encoding works as follows:
- minified names are written as a list of names and indices, in pairs.
{'n1': 1, 'n2': 2} => 'n1,1,n2,2'
- frames are encoded using a sequence of values with markers for the different
kind of frames. Numbers are encoded using VLQ deltas. We use VLQ because it's
already available to any parser that deals with the mappings).
This change also uses the dart2js_tools parser implementation for all unit tests.

This change improves DDC/DDK source maps:
- fix Analyzer backend step locations to pass all of the tests
Kernel was passing. Also improves breakpoints and code coverage.
- fix Analyzer backend to mark hover spans where possible, such as
fields, parameters, locals, `this`, properties, methods, etc.
- refactor DDC/DDK backends to emit source locations, rather than
pointers to Analyzer/Kernel tree nodes.
- unify/simplify source_map_printer between Analyzer/Kernel backends.
- source_map_printer understands JS expression nesting, marking the
innermost JS expression offset corresponding to a given Dart offset.
This preserves hover tooltips, even for expressions with implicit
coercions (e.g. `dart.test(x)`)
- source_map_printer understands that JS end-of-function markings need
to be before the closing brace.
- merge _visitAndMarkExpression and _visitExpression to simplify
Analyzer & Kernel backends.
- fix test expectations where the column location was too specific.
- adds a message to the stepping test runner to help future debugging.
- removes optional destructuring support from Analyzer backend. This
was unused/untested and added complexity. Instead we should decide
if/when to fully switch to destructuring, and then do so.
