Implement API to animate bubble bar position

Create a new API to animate bubble bar position.
Animating it will not update its laid out location.
To update bubble bar laid out location, BubbleBarUpdate can be used.
Applying a location change from BubbleBarUpdate no longer animates the
change.

Bug: 330585402
Flag: ACONFIG com.android.wm.shell.enable_bubble_bar DEVELOPMENT
Test: long press bubble bar and drag it to left and right
