Stash the taskbar on every bubble bar expansion

Added logic to enable BubbleBarView to  notify BubbleBarViewController
of expanded state change. Also updated all the test that uses
BubbleBarView to pass empty Controller.

Fixes: 411304392
Flag: com.android.wm.shell.enable_bubble_bar
Test: Manual. Go to any app. Swipe up to show the taskbar. Trigger any
bubble. Observe taskbar is stashed on bubble bar expanded.
