Revert "Handle direction control in compositor Animations"

This reverts: https://src.chromium.org/viewvc/blink?revision=170491&view=revision

Failed attempt to land two-sided patch. The chromium side broke the blink build and then this patch further broke it after the chromium side was reverted.

In the future, please do a three-step commit if that's required to ensure no build breakage.
