Use BubbleBarLayerView & BubbleBarExpandedView

* Adds BubbleBarLayerView to BubbleController, if the bubble
  bar is active, BBLV will be used instead of BubbleStackView. Some
  methods in BubbleController are updated to account for BBLV.

* Updates the BubbleViewInfoTask (the inflation code for bubbles) to
  expect either BubbleBarExpandedView OR the BadgedImageView and
  BubbleExpandedView used when bubbles are NOT in the bubble bar.
  When showing in the bubble bar, BubbleBarExpandedView will be the
  only view inflated.
