Tearoffs are now represented as a closure that resolves an underlying bound context and property on access. `_boundMethod` and RTI getters must also be evaluated late.
Additionally, we now both canonicalize static methods and tag them with their types at class-declaration time (though lazily) - so that late resolved closures have access to their types.
Some tests have been updated to expect simpler errors. DDC traditionally emits slightly different errors that might aid in debugging.

- Since libraries can't be exposed anymore with the new module
format, relies on "this" and the JS foreign function to get the
current library so we can only test the formatting of libraries.
Patches in a link function to match the behavior of the new
module system.
- Cleans up some unnecessary code to support old type system.
- Adds a status file to skip this test in d8 (it's currently
failing).

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.

* Never iterating an iterable, always converting it
using `.toList()` first and iterating using indices
(fx `setEquals`).
Also require a `List` in places where an `Iterable`

* Avoid doing complicated computations that are also
used for the error message. Do simple check first,
then recompute to get better error messages
(fx `allDistinct`).
Renamed some rarely used members for consistency
(`stringContainsInOrder`->`containsInOrder`,
where other string-contains functions just start
with `contains`, and `containsOneOf` -> `containsAny`
to match `Iterable.any` phrasing, and also it accepts
if containing at least one, not precisely one.)

Moved `assertStatementsEnabled` to `variations.dart` as `asserts`.
Removed `typeAssertionsEnabled` and `checkedModeEnabled`. The former used in one place, where it was replaced with `checkedImplicitDowncasts` from `variations.dart`, the latter wasn't used anywhere.
Deprecates `package:expect/minitest.dart`. It was never intended

Since we lower @staticInterop members differently, CFE expectations are
updated. A previous patchset updated tests to account for changes in
top-level external members, but those changes are now non-breaking.
This CL still keeps some of those fixes to tests since they are more
sound and correct:
- Debugger tests to allowInterop a function that wasn't caught before,
as DDC only adds checks for arguments whose static type is a Function,
whereas js_util does a runtime is check to determine if the argument is
a Function
- Interop tests that typed top-level externals unsoundly
- Interop tests that used tear-offs of top-level external methods
instead of getters

This CL:
- Fixes https://github.com/dart-lang/sdk/issues/43987 (an exception in custom formatting code)
- Restores (most of) debugger_test.dart to passing (which tests above)
- Fixes a type caching error also exposed by the above test
Note, this skips the golden file comparison. That appears to be very broken
