Migrate BubbleController to DisplayImeController

This change is a no-op that migrates off of PinnedTaskController
and instead uses DisplayImeController to react to IME visibility
and position changes. The new API will allow us to hook into the IME
animation so that we can animate the expanded view together with
the IME.

One notable change here is that the new API reports the real IME height,
whereas the previous API sent the height of the area where the IME
overlaps with the window, in our case the Bubble window, excluding insets.
To keep changes here to a minimum, we adjust the height when it is set in
the positioner to account for insets.
