0027540: Run-to-run differences in the 3D Offset algorithm

Browse Source 
Calculating the offset vertices by the superposition of intersection vertices
between pairs of edges (BRepOffset_Inter2d::FuseVertices()).

To obtain stable result when calculating the superposition of vertices
they are sorted (BOPTools_AlgoTools::MakeVertex()).

The support of vertices has been added in nexplode command.

Small correction of tests cases for issue CR27540
