media/gpu/v4l2ip: finish conversion to V4L2Queue

Now that all the required building blocks are in place, we can
transition the CAPTURE queue of the V4L2IP to a V4L2Queue. This allows
us to dramatically reduce its complexity: the OutputRecord becomes
useless, and we can work internally with VideoFrames.
