Fix to cache correct PathToNode in artifact graph (#6632)

* Add NodePath to artifact graph

Since this is cached, this should make PathToNode computation correct
even when code is formatted, whitespace changes, and source ranges
are different.

* Remove dead code

* Add unit tests

* Add tests for PathToNode conversion

* Remove unused parameter

* Add missing PathToNode cases

* Fix to handle unlabeled arg

* Cherry pick unlabeled arg fix

* Change PathToNode comment to match TS implementation
