[PiP2] Add PipExpandAnimatorTest
Added the PipExpandAnimatorTest for PipExpandAnimator class.
PipExpandAnimator class is optimized for testing as well in this change
- Allow supplying SurfaceControlTransactionFactory for testing purpose
- Use the local animation listener since they are implementation details
- Switch over to AnimatorListenerAdapter to avoid unnecessary,
un-testable functions such as onAnimationRepeat
