BRepMesh should decrease deflection for edges of suspected wires only

BRepMesh_FastDiscret decreases deflection of edges of whole shape in case if BRepMesh_SelfIntersectingWire flag is noticed by face checker. However, it leads to increasing of discretization points even for those edges that are not included in intersecting wires. The consequence is the much more complicated mesh could be produced that means an extra time spent by BRepMesh_Delaun and BRepMesh_FastDiscretFace.

It is proposed to identify wires that are rejected by face checker and decrease deflection only for their edges.
