 camerad: rename variables&functions to follow new convention (#20096)

* rename CameraState variables to follow new convention

* continue

* rename camera_process functions

* qcom:rename exposure related variables

* continue

* update commments

* bool real -> bool is_road_cam

* rename sm_front -> sm

* remove paramater tname from start_process_thread

* rename rhd_front to is_rhd

* remove unused varialble name from struct CameraInfo

* rename env_send_xxx

* rename cap_front to cap_driver,cap_rear to cap_road

* rename xxx_camera_process to process_xxx_camera

* update snapshot.py
