features: add virgl to the GL features list

This hopefully adds virgl to the correct places and current statuses
of various extensions.

virgl of course relies on two external things
a) host driver that can support the features
b) up to date host virglrenderer library that can support the features.

This list will be maintained as latest (a) + (b) + mesa.
