Add NotificationListener to launcher.

- NotificationListener extends NotificationListenerService, and is
  added to the manifest.
- Added PopupDataProvider, which contains logic for storing and
  interacting with data that goes into the long-press popup menu
  (shortcuts and notifications). A follow-up CL will rename
  DeepShortcutsContainer to a generic PopupContainerWithArrow.
- If Launcher has notification access, NotificationListener will
  get callbacks when notifications are posted and removed; upon
  receiving these callbacks, NotificationListener passes them to
  PopupDataProvider via a NotificationsChangedListener interface.
- Upon receiving the changed notifications, PopupDataProvider maps
  them to the corresponding package/user and tells launcher to
  update relevant icons on the workspace and all apps.

This is guarded by FeatureFlags.BADGE_ICONS.
