0024596: Slow import of IGES data

Part 1: Speed up of import functionality.
Correction in ShapeFix_IntersectionTool::FixIntersectingWires() - preliminary construction of ShapeAnalysis_Surface tool for the whole face; computation of 2d bounding boxes for edges and wires before intersection checking.

Part 2: Speed up of check shape.
Correction in BRepCheck_Face::IntersectWires() in the same way: preliminary computation of 2d boxes for edges and wires in order to reduce the number of calls of intersection tool for pair of wires.
