Add location as a Inline list payload

The inline payload is added to security settings because
security settings indexes the setting with the key
"location" which corresponds with the correct
PreferenceController, LocationPreferenceController.

However, we suppress the Location search result, so to
avoid confusion later, we don't include the ResultPayload
in the search indexing.
