0031425: Visualization - free Edge has selection sensitivity inconsistent to presentation

Browse Source 
BRepTools::Triangulation() has been extended with a new parameter for checking Poly_Polygon3D presense within free Edges.
StdPrs_WFShape::Add() now performs auto-triangulation in the same way as StdPrs_ShadedShape::Add().
StdSelect_BRepSelectionTool::GetEdgeSensitive() now creates Select3D_SensitiveSegment instead of Select3D_SensitiveCurve for tessellated segment.
Select3D_SensitiveSegment default sensitivity factor has been changed to 3 pixels to match Select3D_SensitiveCurve.

Test case bug23625_1, added workaround for out-of-range crash in HLRBRep_PolyAlgo on re-triangulated shape.
