- 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. Bug: 32410600 Change-Id: I59aeb31a7f92399c9c4b831ab551e51e13f44f5c
