drm/xe/guc: Add missing H2G error code definitions

drm/xe/guc: Add missing H2G error code definitions

These error codes are not actually used in the driver but it is
extremely useful to have them available to understand error messages.

v2: Add a bunch more error codes and drop 'status' from names (review
feedback by Michal W).
v3: Drop 'SUCCESS' response as meaningless in current API (review
feedback by Michal W).
