drm/i915/xehp: CCS shares the render reset domain

The reset domain is shared between render and all compute engines,
so resetting one will affect the others.

Note:  Before performing a reset on an RCS or CCS engine, the GuC will
attempt to preempt-to-idle the other non-hung RCS/CCS engines to avoid
impacting other clients (since some shared modules will be reset).  If
other engines are executing non-preemptable workloads, the impact is
unavoidable and some work may be lost.
