outline: Switch the outline search to use fuzzy_nucleo (#56477)

Nucleo tracking issue:
https://github.com/zed-industries/zed/issues/55872

This PR switches the outline picker to use `fuzzy_nucleo`. 

with that I refactored the outline fuzzy picking to take advantage of
nucleo and its multi-atom query support. The previous implementation had
a lot going on specifically to work around the lack of multiple atoms,
basically taking matters into its own hands to accomplish the same goals
within the constraints it had.

Instead of having two lists of candidates that we have to run the query
against, we just run a single query and take advantage of the fact that
nucleo chooses the matches that are the furtherest towards the end of
the haystack to implement the same ancestor/leaf filtering. It retains
the leaf only matching on single atom queries.
