Add FakeImageSources and simulation functions for testing

This change introduces a dedicated provider interface for creating
ImageSource(s) in CameraPipe, which allows for CameraGraphs to:

- Simulate fake images during tests
- Simulate fake images for all requests during tests
- Check that all simulated images have been closed
- Check that all fake ImageReaders and ImageSources have been closed
- Inspect all CameraGraphs that have been created via a
  CameraPipeSimulator interface.

This change also causes CameraGraphSimulator and CameraPipeSimulator
to extend their respective interfaces by delegation, which ensures
that the underlying behavior remains in sync with the real CameraPipe
and CameraGraph implementations.

Test: ./gradlew\
      :camera:camera-camera2-pipe:testDebugUnitTest\
      :camera:camera-camera2-pipe-testing:testDebugUnitTest\
