**`(chore):`** \* Add `ServiceTypeReferenceInfo` to IR so that generators can recognize what types are referenced from exactly one service (@amckinney).

```yaml
  ServiceTypeReferenceInfo:
    properties:
      typesReferencedOnlyByService:
        docs: "Types referenced by exactly one service."
        type: `map<commons.ServiceId, list<commons.TypeId>>`
      sharedTypes:
        docs: "Types referenced by either zero or multiple services."
        type: `list<commons.TypeId>`
```
