[CM] Onboard maps to cross-type search (#155148)

## Summary

Part of #152224
Follow up to #153256

This PR onboards maps CM integration into the multi-type search
(`msearch`). It isn't actually used anywhere in the user-facing UI yet,
as first other types need to be migrated to CM.

This PR also adds an example app to test the `msearch` end-to-end.
