Moves minimization change handling into NotificationEntryListeners.

This change moves the logic in NotificationEntryManager which was
explicitly handling changes in whether a row was minimized or not after
it was reinflated into the target components through the normal listener
mechanism.  This involves VisualStabilityManager registering a
NotificationEntryListener and allows us to remove the dependency of
NotificationEntryManager on VisualStabilityManager.
