libcamera: camera_sensor: Make V4L2_CID_EXPOSURE mandatory

Add the V4L2_CID_EXPOSURE control to the list of mandatory controls the
sensor driver has to report and document this new requirement.

While at it, re-sort the mandatory V4L2 controls in alphabetical
order in the CameraSensor class and remove the above comment as
the usage of the controls is better reported in the documentation.
