Transitions - Add more source data, refine existing transitions

Data sources - Listen for events from the BiometricUnlockController
and KeyguardStateController#isBouncerShowing

Repositories - Add isBouncerShowing and WakeAndUnlock events into
KeyguardRepository

Interactors - Refine keyguard transitions so that states are more
accurate

BiometricUnlockController - Allow multiple listeners so that events
can make it into the KeyguardRepository. Cleanup redundant callback.

Test: ClockEventControllerTest KeyguardRepositoryImplTest
KeyguardTransitionRepositoryTest KeyguardTransitionInteractorTest
BiometricsUnlockControllerTest CentralSurfacesImplTest
Bug: 195430376
