Error on tessellation request in IFC2X3

Browse Source 
IfcTriangulatedFaceSet/IfcPolygonalFaceSet were introduced in
Fix #7992: IFC4 and do not exist in IFC2X3. Previously, requesting an
IfcTessellatedFaceSet representation in an IFC2X3 file silently
fell back to a faceted brep after unassigning material sets.
Add a guard in the update_representation operator (user-facing
error) and in the add_representation API (ValueError) so the
unsupported request is caught instead of failing silently.

Generated with the assistance of an AI coding tool.
