Explore registrar-based API for search bar.
This commit adds a Registrar trait for use by search crate. Registrar can register actions on some target and search can utilize that trait to opaquely add actions on that target. Notably, search is now opt-in (it always was in zed2 actually). Having editor doesn't make it searchable straight out of the gate. You might have to call BufferSearchBar::new a bunch more.
