Camera2: Use scene mode override parameter

- Read in SCENE_MODE_OVERRIDES static parameter if available.
  Use it to select AF/AE/AWB modes when a scene mode is set.
- Add quirks structure to parameters; not yet used
- Fix desynchronization between range and single FPS value.
  Still need to sort out best way to convert from one to another.
