vd_lavc: move entrypoint for hwframes_refine

The idea is to get rid of vd_lavc_hwdec, so special functionality like
this has to go somewhere else. At this point, hwframes_refine is only
needed for d3d11, and it doesn't do much, so for now the new callback
has no context. In can be made more fancy if really needed.
