Lasse R.H. Nielsen f8086c81ae Collect all test-related files in package:expect.
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.
