0028191: Inefficient implementation of the BRepOffset_Tool::HasCommonShapes() method

The method to find common Vertices and Edges between faces
  BRepOffset_Tool::HasCommonShapes(const TopoDS_Face&,
                                   const TopoDS_Face&,
                                   TopTools_ListOfShape&,
                                   TopTools_ListOfShape&)

has been re-implemented using maps and renamed to BRepOffset_Tool::FindCommonShapes.

The new method
  BRepOffset_Tool::FindCommonShapes(const TopoDS_Shape&,
                                    const TopoDS_Shape&,
                                    const TopAbs_ShapeEnum,
                                    TopTools_ListOfShape&)

has been implemented to look for the common shapes of given type.
