Add a perf test for picture raster cache (#45050)
This will catch issues like
https://github.com/flutter/flutter/issues/44252, and this test is
inspired by the `list_demo` sample app in
https://github.com/flutter/flutter/issues/43083#issue-509586473

This is tested locally on a Moto G4 before and after the fix
https://github.com/flutter/engine/pull/13710

The `average_frame_rasterizer_time_millis` of this test drops from
~5.4ms to ~4.9ms after that fix.

Notes

Note on Gradle wrapper files in .gitignore:

Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
