Refactor the Centroid node and Subpath struct and methods to use Kurbo, eliminating all remaining usages of Bezier-rs (#3036)

Browse Source 
* define Subpath struct in gcore and refactor node-graph

* Refactor few methods

* refactoring worked!

* refactor centoid area and length

* remove unused

* cleanup

* fix pathseg_points function

* fix tranforming segments

* fix segment intersection

* refactor to_path_segments fn in gpath-bool crate

* refactor gcraft

* add bezier-rs dep

* Code review the editor directory

* use path-bool for solving roots

* Code review
