COMPACTION_STATUS resp. ZONE_TYPE are currently used to translate enum compact_result resp. struct zone index into their symbolic names for an easier post processing. The follow up patch would like to reuse this as well. The code involves some preprocessor black magic which is better not duplicated elsewhere so move it to a common mm tracing relate header.
