Refactored testCropWithChildBoundingInsets to avoid recording

testCropWithChildBoundingInsets only needs a single frame since there is
no animation running. Move testCropWithChildBoundingInsets to
AttachedSurfaceControlTest and capture a screenshot of the activity when
everything is set up. This avoids the overhead of setting up a
screenrecording and avoids any issues system content on screen that
makes the test flaky.
