libs: decoder: Add decode_with_surface_id for AV1 film_grain.

Browse source 
The AV1 film_graim feature needs two surfaces the same time for
decoding. One is for recon surface which will be used as reference
later, and the other one is for display. The GstVaapiPicture should
contain the surface for display, while the vaBeginPicture() need
the recon surface as the target.
We add a gst_vaapi_picture_decode_with_surface_id API to handle this
kind of requirement.
