hi846: support more v4l2 controls

libcamera, when starting, says about hi846:

[1:05:48.045264498] [4489]  WARN CameraSensor camera_sensor.cpp:196 'hi846 2-0020': Recommended V4L2 control 0x009a0922 not supported
[1:05:48.045374180] [4489]  WARN CameraSensor camera_sensor.cpp:248 'hi846 2-0020': The sensor kernel driver needs to be fixed
[1:05:48.045406100] [4489]  WARN CameraSensor camera_sensor.cpp:250 'hi846 2-0020': See Documentation/sensor_driver_requirements.rst in the libcamera sources for more information

that should be V4L2_CID_IMAGE_STABILIZATION.

but also, V4L2_CID_CAMERA_ORIENTATION and V4L2_CID_CAMERA_SENSOR_ROTATION should be added, to describe the mounting position.

and consider adding hi846 to src/libcamera/camera_sensor_properties.cpp if it makes sense
