0031479: Modeling Algorithms - exception on geometry transformation of triangulation-only shapes (without geometry surface)

Browse Source 
* Avoid crash in BRepBuilderAPI_GTransform algorithm. The crash in BRepBuilder_Transform has been solved by 0032716.
* Move copying modifier to BRepTools package.
* Implement copying of triangulation in BRepTools_NurbsConvertModification.
* Implement transformation of a triangulation in BRepTools_GTrsfModification.
* Update test case bugs/mesh/bug22778 to clean the triangulation after conversion to NURBS (reproduce the same behavior as before).
