drm/xe/rtp: Add match for render reset domain

This allows to create WA/tuning rules that match the first engine that
is either of compute or render class. This matters for platforms that
don't have a render engine and that may have arbitrary compute engines
fused off: some register programming need to be added to one of those
engines.
