Convert all SCREEN_OFF receivers to BroadcastDispatcher

All broadcast receivers that filter for ACTION_SCREEN_OFF have been converted
to register with BroadcastDispatcher instead of Context. In many cases
this involves other Intents being covered by BroadcastDispatcher.

Additionally, UserBroadcastDispatcher propagates the PendingResult so
the individual receivers can access it (mostly to query getSendingUser).

Test: enable logging of BroadcastQueue for ACTION_SCREEN_OFF only shows 2
receivers (user 0 and user -1)
Test: Dump of BroadcastDispatcher shows all the classes registered to it
Test: enable logging of UserBroadcastDispatcher
Test: atest PowerUITest StatusBarTest VolumeDialogControllerImplTest
        SystemUIDialogTest NavigationBarFragmentTest
