0025518: Colors are not written to IGES 5.3

Browse Source 
Writing of colors to IGES Face (510) and Solid (186) entities allowed since this is used by CAD systems (even if not allowed by IGES standard).
Color assigned to surface, face and solid entities to ensure that different CAD systems will recognize them.

Test-case for issue #25518
