Get the view to be used as qsb bar from the launcher directly.

This will allow more control over the qsb visuals and behaviour in GEL.
Depends on ag/339203

Future changes:
- revert ag/344333 since we won't need the normal qsb to support hotword
  anymore
- Dragging icons over the Drop target bar (to remove/uninstall them or
  get App info) doesn't currently work in GEL. There might be future
  changes needed to fix that.
