Set proper interpolators and durations for the bubble bar animations
Set proper interpolator and duration for bubble bar expansion and
collapsing animation. Also set animation properties for the taskbar
fade in and out animations.
Flag: com.android.wm.shell.enable_bubble_bar
Test: Manual. Expand / collapse bubble bar when taskbar is pinned and
expanded bubble bar would intersect the task bar.
Fixes: 360821863
