libcamera: pipeline_handler: Remove Camera argument from request handling
There is no need to pass the Camera pointer to queueRequest(), completeBuffer() and completeRequest() as the Request also passed contains the same information. Remove the Camera argument to avoid situations where the information in the Request and the argument differ. There is no functional change and no public API change as the interface is only used between the Camera and PipelineHandler.
