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.
