This reverts commit a44f174e.

Reason: start_up tests become flaky.

See https://github.com/flutter/flutter/issues/28374

Merge on red to fix the tree

This patch adds a default shader warm up process which moves shader compilation from the animation time to the startup time. This also provides an extension for `runApp` so developers can customize the warm up process.

This should reduce our worst_frame_rasterizer_time_millis from ~100ms to ~20-30ms for both flutter_gallery and complex_layout benchmarks. Besides, this should also have a significant improvement on 90th and 99th percentile time (50%-100% speedup in some cases, but I haven't tested them thoroughly; I'll let our device lab collect the data afterwards).

The tradeoff the is the startup time (time to first frame). Our `flutter run --profile --trace-startup` seems to be a little noisy and I see about 100ms-200ms increase in that measurement for complex_layout and flutter_gallery. Note that this only happens on the first run after install or data wipe. Later the Skia persistent cache will remove the overhead.

This also adds a cubic_bezier benchmark to test the custom shader warm up process.

This should fix https://github.com/flutter/flutter/issues/813 (either by `defaultShaderWarmUp`, or a `customShaderWarmUp`).

* Cirrus re-run...

* Fix condition check

* rename props, add docs, rename method

* fix tests after param changes

* Fix weird path for flutter run and add tests

* remove print, fix tests

Fix the length of the valueHelp on the --sample option for the create command, and turn on wrapping. (#28264)

The wrapping for some commands was never actually turned on, so this turns it on.

Also, it shortens the `valueHelp` for the `--sample` option to be just "id" instead of "the sample ID of the desired sample from the API documentation website (http://docs.flutter.io)", which was causing the line to get far too long.

Fixes #23074

* reduce iterations to avoid test timing out

This reverts commit 1c021506.

The pre-commit tests never actually ran, so it looked green when it wasn't. This breaks 16 tests that depend on the argument existing, even though it isn't actually used.

This command line argument has already been removed in the main
Dart repository, so building flutter with the latest dart fails.
