0028403: Avoid useless calls to BRepTools::Write()

Useless writes of intermediate shapes to hardcoded paths are removed in samples\mfc\standard\02_Modeling\src\ModelingDoc.cpp

Methods IGESBRep::WriteShape(), XSControl_Utils::WriteShape() are deleted; BRepTools::Write() can be used instead.
Method TopOpeBRepBuild_Tools::DumpMapOfShapeWithState() is moved to where it is used -- TopOpeBRepBuild_Builder1_1.cxx as static function (commented out).

Unused DRAW command OCC18612 is removed.

Upgrade Guide is corrected to avoid Doxygen warnings.
