17219 FIX gcp_status: Fix KeyError: 'global'

This change affects users which have configured the rule 'Google Cloud Platform (GCP) Status'.
Previously, Checkmk did not handle incidents correctly, which had set `global` as an associated location.
This was the corresponding traceback:
```
  File "/omd/sites/mon_home/lib/python3/cmk/plugins/gcp/agent_based/gcp_status.py", line 72, in parse
    data.setdefault(constants.RegionMap[location.id_], []).append(incident)
KeyError: 'global'
```
With this werk, the crash is fixed.
