plugins: video memory: Add a GST_MAP_VAAPI flag to peek the surface.

Browse source 
Just like what we do in VA plugins, the GST_MAP_VAAPI can directly
peek the surface of the VA buffers. The old flag 0 just peek the
surface proxy, which may not be convenient for the users who do not
want to include our headers.
