libcamera: pipeline_handler: Pass a non-const Camera to methods

The start(), stop() and queueRequest() methods receive a const pointer
to the related Camera object. The stop() request will need to modify the
state of the camera, in order to report completion of pending requests.
Un-constify the Camera pointer to that method, and update the start()
and queueRequest() methods similarly for coherency.
