mesa_glinterop: make GL interop version field bidirectional
This allows clear and easy communication between the two.
Caller: Requesting information (struct vN)
Callee: I know how to deal with older version (vN-1) only. Here is your
data and the version I support.
Caller: Older version ? Sure I'll cap all access to the fields provided
by the older version (vN-1)
