Ensure Animators and AnimatorSets run together are sync'd

Bug 18122022

Previously, each animator would wait a frame after it was
started the animation was actually started. This is fine
for the first frame of an animation, but when it is within
an AnimatorSet, each animator will add a frame of delay.
This skews the animations so that they can no longer be
synchronized.

This CL refrains from waiting for an animation frame when it
is started during the animator callback and just start
the animation immediately on that frame.
