Notify the host when the insets animation running state is changed 

This helps the UI toolkit control the frame rate while there is any
insets animation running.

Bug: 300019131
Test: Add local logs to see if notifyInsetsAnimationRunningStateChanged
      is called as expected while playing insets animations.
