License update (#45373)
* Update project.pbxproj files to say Flutter rather than Chromium

Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.

* Update the copyright notice checker to require a standard notice on all files

* Update copyrights on Dart files. (This was a mechanical commit.)

* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.

Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).

* Clean up the copyrights in non-Dart files. (Manual edits.)

Also, make sure templates don't have copyrights.

* Fix some more ORGANIZATIONNAMEs

Add test case for Flutter Issue #27677 as a benchmark. (#34870)
* Add test case for Flutter Issue #27677 as a benchmark.

See https://github.com/flutter/flutter/issues/27677

I got the following results running the test on a Moto E2 which
will help us determine how much we can gain by analyzing the
operations and eliminating unnecessary repaints based on
dirty rectangles/regions.

no blurs       - avg 216.0 fps over 3 samples
blur the group - avg  22.9 fps over 3 samples
blur each txt  - avg   3.4 fps over 3 samples

* Added the new benchmark to be tracked on the dashboard.

Reland "Shader warm up (#27660)" (#28537)
This reverts commit adc8e159a5.

This should be safe to land once https://github.com/flutter/flutter/pull/28530 gets merged

Merge on yellow doc test because the doc test is actually green.

Shader warm up (#27660)
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`).
