Add gst_vaapi_surface_proxy_copy() function that creates a new surface proxy with the same information from the parent proxy, except that the user-defined destroy notify function is not copied over. The underlying VA surface is pushed back to the video pool only when the last reference to the parent surface proxy is released.
