This CL introduces the first combination of `external const factory`
with `@patch const factory (.*) = (.*)`. This specific combination was
never used in the core libraries, and did not work.
Half of the fix is a missing flag from the CFE:
https://dart-review.googlesource.com/c/sdk/+/187440
The other half of the fix is matching on the
kRedirectingFactoryConstructor tag, and allowing constructor names
in procedure targets (even though we never compile those expressions
because they are invalid).

Adds support for single dimension inline arrays in structs. Multi-
dimensional arrays will be supported in a future CL.
This CL adds:
- CFE static error checks for inline arrays.
- CFE transformations for inline arrays.
- VM consumption of inline array fields for NativeType.
- Test generator support for inline arrays + generated tests.
Previous CLs added support for inline arrays in:
- analyzer https://dart-review.googlesource.com/c/sdk/+/183684
- updated in this CL to new API.
- ABI calculation https://dart-review.googlesource.com/c/sdk/+/183682
Closes: https://github.com/dart-lang/sdk/issues/35763
Open issue: https://github.com/dart-lang/sdk/issues/45101
CFE transformations are tested with expectation files:
TEST=pkg/front_end/testcases/(.*)/ffi_struct_inline_array.dart
Trampolines and CArray API are tested with end-to-end Dart tests:
TEST=tests/ffi(_2)/(.*)by_value(.*)test.dart
TEST=tests/ffi(_2)/inline_array_test.dart
Compile-time errors (both CFE and analyzer) are tested in:

This changes the CFE expectation test suites to use unsound null safety
as default to avoid passing --enable-experiments=no-non-nullable to opt
out old test folders.
This change removes most test folders from the 'strong' tester, since
this now only supports sound null safety, which requires all libraries
to be opted in. Instead, the 'weak' tester now runs all test folders.
Additionally the 'outline' tester is changed to use unsound null safety
so that it call be used on all test folders.
The 'fast_strong' tester is removed since it should just be run locally
and it can be run by passing an option to the other testers.
References to non-existing 'shaker' folder has been removed from
testing.json.

Does not remove the entry-point from the constructor yet, because FFI

G3 has been migrated (go/dart-ffi-1.0-g3-migration), so now we can roll
the package version which has all the deprecated methods removed.
Rolling `package:ffi` forward also means it is no longer using
`sizeOf<T>()` generically. So the problems in the CFE expect files
disappear.

it easier to add more data in subsequent CLs.
Extends `FindPragma` to allow returning multiple matched pragma's, so

Members declared in mixins are treated as if these were declared in
the class where they are mixed in. This means that use their types as
declared types, instead of including them in a combined member signature.
This failed in the case where a member was synthetically added to the
mixin class, because the types of these we wrongfully be handled as
declared types.
We now skip all synthetic members when reasoning about mixed in members
as declared members.

The analyzer and CFE now report a warning on calls to

`sizeOf<T extends NativeType>()` where `T` is a generic.
Adapted from https://dart-review.googlesource.com/c/sdk/+/178200 to
only deprecate but not error out on generic calls.
Does not roll forward `package:ffi` to a version with the `Allocator`
but keeps the generic `sizeOf` invocation. This causes extra warnings
in the pkg/front_end testcases.

This CL introduces a 'semi-fuzz' option in the strong tests, that is
disabled by default.
The current version just compiles with the incremental compiler
and invalidate one file at a time, seing that we get the same
libaries in the output and that we either get errors in both cases
or no errors in both cases.
Future versions should for instance split libraries into more
libraries or parts etc., and the semiFuzz option should be enabled
by default.

A factory is saved as a procedure in kernel, and was thus also indexed
as a procedure for the purpose of experimental invalidation.
This caused trouble when having a "real" procedure and a factory with
the same name.
That is fixed by this CL by indexing factories ad constructors.
