[PATCH v4 14/32] drm/xe/ras: Check RAS and LOG component definitions

While not strictly required, we want to make sure that components
definitions used by the RAS firmware are in the same fixed relation
with HW components definitions used by the LOG infrastructure to
allow code simplification. Add static asserts to enforce that.
