User has no possibility to change Sill parameter upon adding Window, it
is only possible while creating Window for the first time.
So this patch adds this parameter, and changing it moves the *BASE*
coordinate of the object in Z direction.
* [ArchWindow] Improve SubVolume() HoleDepth deduction algorithm
https://github.com/FreeCAD/FreeCAD/issues/19559https://forum.freecad.org/viewtopic.php?t=92360https://forum.freecad.org/viewtopic.php?p=812844#p812844
Current HoldeDepth deduction algorithm is too 'agressive' and may punch holes in adjacent wall segment.
With improved algorithm, ArchComponent pass the Window's host information to ArchWindow getSubVolume() to deduce HoleDepth taking into account of Wall's Width /getWidths for Wall Base is ArchSkech
TODO: For future development - More robust approach
With ArchSketch, on which wall segment an ArchObject is attached to is declared by user and saved.
The extrusion of each wall segment could be done per segment, and punch hole in the exact wall segment before fusing them all. No need to care about each wall segement thickness.
* [ArchWindow] Typo Lint reported
* [ArchWindow] Fix getSubFace(self) raise NotImplementedError
