nathanrogersgoogle df71c78332 Add a delay to Animator::BeginFrame's NotifyIdle call (flutter/engine#5972) ...

This change adds a delay before Animator::BeginFrame calls its
delegate's OnAnimatorNotifyIdle.  This is because under certain
workloads, such as our parent view resizing us, which is communicated
via viewport change events, we won't have a frame scheduled yet in the
animator, despite the fact that we will go on to schedule a frame once
the viewport event arrives.

In Fuchsia's resizing performance test, on our reference high end x86-64
hardware, the previous logic was resulting in a ~45ms garbage collection
right after the first frame of an animation.
