Add a GraphProcessor to CameraPipe

The GraphProcessor is responsible for keeping track of state across
1 or more Camera2 CameraCaptureSessions and for dispatching updates to
the camera on background thread(s). All of the interactions with the
camera go through a RequestProcessor interface that wrap a Camera2
CaptureSession.

Test: Existing unit tests continue to pass.
Test: Added coroutine-based tests for the GraphProcessor
Test: Added Fake objects to test interactions
