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.
