intel: Add an env var override to execute for a different GPU revision.

Browse source 
Sometimes I'm on the train and want to just read what's generated
under INTEL_DEBUG=vs,wm for some code on another generation.  Or, for
the next gen enablement we'll want to dump aub files before we have
the actual hardware.  This will let us do that.
