Remove unused ChangeId in AnimationUtils

Remove unused ChangeId in AnimationUtils that leads to a bug.
Originally, I planned to apply Compat Framework to gate the code change
for VRR, but I switched to Trunk Stable Flag once it's ready.

I will revisit the usage Compat Framework later if it would benefit our
project.
