uvc: Handle UVC events internally in uvc.c

The event notifier for the UVC device is registered in
uvc_stream_set_event_handler(), which requires exposing the
uvc_events_process() event handler to the uvc_stream class.

Make the event handler internal by registering it in uvc_events_init().
This requires passing the uvc_stream pointer to the uvc_open() function
and storing it internally in the uvc_device object.
