[CM] Onboard maps to cross-type search

[Dosant]

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.

Overall looks great! I left a few comments around typings.

Would the examples work better together if they both work with the "todos" content type?
