Camera: Rename new API to camera2, rearrange camera service
- Support API rename from photography to camera2
- Reorganize camera service files
- API support files to api1/, api2/, api_pro/
- HAL device support files into device{1,2,3}/
- Common files into common/
- Camera service remains at top-level
