Inset the bubble bar expanded view instead of drawing our own header
* Use new method on TaskView to inset the app content when showing
in bubble bar
* Update the visuals of the handle in the bubble bar expanded view to
show three dots instead of a bar
* Make the header area a bit smaller (40 -> 32dp)
* Use a touch delegate to extend the touch area of the three dots
past the top of the expanded view so that it's a 48dp height touch
target.
Test: manual - enable bubble bar, get a bubble, expand it
=> observe the appearance of the header, should be 3 dots
centered in the bar)
=> ensure that tapping slightly above the top edge of
the expanded view triggers the menu
