preview tabs: Support find all references (#10470)

Bennet Bo Fenner created 2 years ago

`FindAllReferences` will now open a preview tab, jumping to a definition
will also open a preview tab.


https://github.com/zed-industries/zed/assets/53836821/fa3db1fd-ccb3-4559-b3d2-b1fe57f86481

Note: One thing I would like to improve here is also adding support for
reopening `FindAllReferences` using the navigation history. As of now
the navigation history is lacking support for reopening items other then
project files, which needs to be implemented first.

Release Notes:

- N/A
