Summary: Ref T13079. This recently-introduced Engine/EngineExtension are a good fit for adding more datasource functions in general, but we didn't think quite big enough in naming them.
Test Plan: Used quick search typeahead, hit applications/users/monograms/symbols/etc.
Maniphest Tasks: T13079

Summary:
Use ClassQuery to find datasources for the quick-search.
Mostly, this allows extensions to add quicksearches.
Test Plan:
using `/typeahead/class/`, tested several search terms that make sense.
Removed the tag interface from a datasource, which removed it from results.
