0028131: BRepOffset_MakeOffset can't create offset with a face which created by filling 3 bsplinecurve

Browse Source 
Handling of degenerated points (with all derivatives zero) in GeomEvaluator_OffsetSurface is improved by iterative movement towards middle of the surface (extension of one-step approach implemented earlier in #28112).
