radeonsi/vcn: data structure av1 enc long term reference.

Browse source 
Here it borrowed the term "long term reference" to represent
the customized reference frame rather than the default ones used.

To enable that, it needs application to leverage VAAPI existing
interface to mark a frame as "long term reference", and then
it will be preserved in the DPB for later usage. This preserved
frame later could be refered to by having its signature used in
the ref_frame_idx[] list, and the index can be indicated by
RefFrameCtrl index2, which has not been used for other purpose.
