[PATH]: Refactor/path module naming cleanup

[mlampert]

Restructure the source code to bring some order into the python modules and make the code more digestible. It does away with most of the naming redundancy and clearly separates business logic from UI dependent code.

This also combines the C++ and python backed object classes in a single namespace. From the python side Log and Geom are pulled into the top level Path namespace due to their universal usage. All other modules are in sub-modules.

Going forward it should be noticeable if a module violates the dependency tree, introduces cyclic references or tries to pull UI logic into the backend business logic. Also, the new structure should be extensible in the future.

Quick initial look seems to work correctly, with a couple of exceptions.

Attempts at 3D Surface and 3D Waterline give error messages.

_SurfaceSupport.ERROR: PSF.isReady() no "Op.Surface" method.
Surface.ERROR: Failed to pre-process model and/or selected face(s).

_SurfaceSupport.ERROR: PSF.isReady() no "Op.Waterline" method.
Waterline.ERROR: Unable to pre-process obj.Base.

Shall I build a snap for testers of this PR ?

@Floriansimmer Is it possible to get any more information about why the github CI is failing? These unit tests pass locally on multiple platforms.

Since this PR is merged I get this error message when starting FreeCAD:

Path WB not found

In the combo box the Path workbench is still listed and when I try to activate this error is raised:

Thanks for letting me know - I'll check it out tonight.

I was able to solve the issue. Previously I've only deleted Mod/Path of my build directory but after realizing that another build works fine I now have deleted src/Mod/Path as well and after rebuilding it the issue is gone.

Fwiw, appears to have happened in this commit

[mlampert]

It seems I messed up a rebase - will fix it tonight - sorry about that.
