Added set of methods CopyVertex in BRepTools_ReShape. Usage of this non-modifying methods added in ShapeFix_Wire, ShapeFix_Edge. Test case for issue 26656. Test cases updated to the new behavior. Correction of test cases for issue CR26656 Changed access by value to access by reference in method CopyVertex.
