libcamera: camera_sensor: Cache mounting orientation instead of transform

Browse source 
The cached rotationTransform_ value is used in computeTransform() only,
to compute the mounting orientation. Cache the mounting orientation
instead, removing the need for the intermediate conversion of the
rotation to a transform.
