Remove animation listeners on cancel

AnimationSet#removeAllListeners does not remove the animations of the
child animators. When we cancel the maximzie window progress animator,
we need the onEnd listener to be cancelled so that the maximize window
does not open.

Bug: 327677202
Test: Exit maximize window before progress animation is complete.
Maximize menu should not open.
