st/va: skeleton VAAPI state tracker

This patch adds a skeleton VA-API state tracker,
which is filled with live in the subsequent patches.

v2: fixes in configure.ac and va state_tracker Makefile.am
v3: do not link against libva.
    detect libva version, and correctly set driver entrypoint name.
    rebase(cleanup) targets/va/Makefile.am
v4: cleanup va version auto detection
    add back targets/va/va.sym
