SysUI changes for setSuppressBubble

1) We need a way to listen for locusId, this is done via
   a new listener on ShellTaskOrganizer that is informed
   for all task info changes.
2) When locusId for focused activity changes, check for
   a bubble in data that has a matching locusId & has
   API set
3) Add suppress/unsuppress in the state change flow and
   update the views

TODO in later CL:
- animate the view being hidden / shown; handle flyout

Test: atest ShellTaskOrganizerTests BubbleDataTest BubbleXmlHelperTest (also CTS CL)
