Add visual stability manager to data-layer

Create OnUserInteractionCallback (to repace OnDimissCallback) which will
handle user interactions with notifications (ExpandableNotificationRow)
and send this information to the relevant notification pipeline.

While we still have both notification pipelines in SystemUI, the new
pipeline will use a VisualStabilityManagerStub (used by
HeadsUpManagerPhone and MediaCarouselController) since the view layer no
longer needs visual stability since this will be taken care of by the
VisualStabilityCoordinator in the data-layer. Once we migrate to the new
pipeline, the legacy VisualStabilityManager + Stub should deleted.

Notes:
- Currently only one coordinator can attach a visual stability manager
or an IllegalStateException will be thrown.
- The suppressed group and section changes are logged in the
suppressedAttachState on the ListAttachState object on each entry.
- Currently we do not suppress the ordering of children as part of the
new VisualStabilityCoordinator; however the old pipeline does
suppress ordering.
