Subject: libcamera: camera_sensor: Expose the Bayer order

Pipeline handlers may need to know the Bayer order produced by the
sensor when a Transform is applied (horizontal or vertical flip). This
is currently implemented manually in the Raspberry Pi pipeline handler.
Move the implementation to the CameraSensor class to make it usable in
other pipeline handlers.
