virgl: Add a caps feature check version
When we add new feature checks on the host side that is used to
enable a cap conditionally that was enabled unconditionally before
we might end up with a feature regression when a new mesa version
is used with an old virglrenderer version that doesn't check for
that cap.
To work around this problem add a version id to the caps that corresponds
to the features that are actually checked on the host and check that
version too when enabling the cap.
