cad/ifcopenshell: add and enable PYTHON option

IfcOpenShell is mainly consumed via python (FreeCAD, Blender). So add this option and set it as default.

While here:
- update ifcopenshell 0.6.0 to latest commit (AFAIK, there is no real versioning atm) allow to build with swig >= 4
- remove patch-cmake_CMakeLists.txt (fixed upstream)
