Remove UV points from BRep data structure

UV points in BRep data structure represent the bounding points of the parametric curve of the edge on the face (data which can be computed on the fly). Analysis of OCCT algorithms shows that UV points are used very rarely, thus it seem unreasonable to keep them.

So, the proposal is to remove the UV points from BRep data structure completely and update all algorithms where this points are used on direct computation of bounding points of parametric curve with D0 method.
