wm4 06b30cc81f vaapi: use libavutil functions for copying hw surfaces to memory
Makes va_surface_download() call mp_image_hw_download() for
libavutil-allocated surfaces, which in turn calls
av_hwframe_transfer_data().

mp_image_hw_download() is actually not specific to vaapi, and can be
used for any hw surface allocated by libavutil.
