[Intel-xe] [PATCH] drm/xe/tuning: Add missing engine class rules for LRC tuning

[Matt Roper]

The LRC tuning settings we have today are modifying registers that are
part of the RCS engine's context; they're not part of the general CSFE
context that would apply to all engines.  Add ENGINE_CLASS(RENDER) to
the RTP rules to properly restrict these to the RCS.

Bspec: 46255, 46261
