[record_use] Add experimental flag and test project - #184719

We resharded the mac build-tests in
#184719.

That required `bringup: true`, the bots are green for the last 3
commits, move them out of bringup.

The timeouts seem better this time. The slowest shard runs in 31
minutes.

The timeouts seem better this time. The slowest shard runs in 31
minutes.

flutter#150642 has been closed saying
that it's fixed.

And also I resharded these bots
(flutter#184719 &
flutter#184738), which likely means
shard 1 now runs different tests than before.

FYI @vashworth @gmackall

Bug:

* dart-lang/native#2690

**Does _not_ add an implementation**, only:
- an experimental flag,
- an integration test that should pass when the experiment is
implemented,
- and the record_use package as an explicit dependency.

Landing this PR first because it's a ton of files. It will keep the
actual implementation PR more reviewable.

Note the test projects go through the usual hoops:

* `flutter create`.
* Add the things we want to test.
* Add copyright headers everywhere.
* Drop all the icons, and modify all the native build files to not refer
to the icons. (Force pushing 10x in the process to get the bots green.)
* The build_tests shards build the test projects for all target OSes
(catching things such as misconfigured icons etc.)

The integration test loosely follows the data assets integration test,
but it only runs release mode (so no hot reload and hot restart).

The integration test uses data assets (not code assets) so that we can
also test the web backends with record-use. This means the integration
test relies on also enabling the data assets experimental flag.
