Subject: [PATCH] [mobar] Fix keyboard accessory overlap in multiwindow

For reasons as yet unknown to me, multi-window seems to cause
ToolbarControlContainer to not be drawn when its pre-translation
position overlaps with the keyboard accessory. This may be an
optimization of sorts; I was not able to turn it off by fiddling with
clipChildren/clipToBounds.

Instead, we resolve it by removing kb accessory height from the
translation calculation, using it instead to set the bottom margin. This
should be safe since we don't use the bottom margin for another purpose
and performant since the keyboard accessory doesn't change height often.

Two related issues are resolved at the same time:
* The revamped kb accessory reports the wrong height, referencing the
  old dimen. This is changed to be feature aware.
* There is no insets animation in multiwindow, meaning minimization
  progress isn't set properly. We now explicitly call it when skipping
  the animation.
