Decouple Injection from subcomponents of PipManager (5/N)

1) PipManager manages all instances and ensure they are singleton
2) BoundsHandler manages singleton PipSnapAlgorithm
3) Remove unnecessary cached context
4) All context dispatch from PipManager
5) Let PipManager manage DisplayController callback
6) Decouple PipSurfaceTransactionHelper from dagger
7) Decouple PipAnimationController from dagger
8) PipTaskOrganizer own singleton PipAnimationController
