i915,r200,radeon,vega: Change vendor from "VMware, Inc." to "Mesa Project".

These are components which were originally developed by Tungsten Graphics,
which was in turn acquired by VMware, but are de facto now being maintained
by third-party contributors of the Mesa open-source community.

This matches what's reported by swrast driver and a few other components.
