Plane Connection Refactor (#4556) (#4565)

* Refactors all plane parts to use a common helper for
calculating connections to adjacent planes.
Also fixes problems with updating these connections on neighbor updates.

* Fix conflicting GuiSync ID.

* Slightly refactor PlaneConnectionHelper, and fix an issue where the bounding box was calculated incorrectly by using the wrong up-direction.

(cherry picked from commit 8617dc8340)
