Implement rotate animation for shared element transition (#6144)

This commit adds support for animating rotate/rotationZ animation during shared element transition.

It also...
* Removes ClipBoundsAnimator - Not sure why I reintroduced it
* Sets pivotX and pivotY only if needed
* Removes "Preview" button in Navigation tab from Android
* Delete ClipBoundsAnimator
