Revert of cc: Make heavy layer tree test more realistic (https://codereview.chromium.org/305903003/)

Reason for revert:
Actually what we had was working fine.

Original issue's description:
> cc: Make heavy layer tree test more realistic
> 
> The heavy layer tree test is supposed to simulate a complex layer tree
> with transform animation. Currently it does so by forcing repaint of all
> layers, but we should only really animate layer transforms to better
> match reality.
