0032692: Mesh - In BRepMesh_ModelPreProcessor avoid crashes with problematic topology

Browse Source 
Improved the processing for the case where Failure flag for the meshing face is set. Specific tests added.
Check triangulation consistency even for shapes with problematic topology given that they are suitable for keeping it.
