IfcAxis2PlacementLinear mapping used with IfcSectionedSurface and IfcSectionedSolidHorizontal

IfcSectionedSurface and IfcSectionedSolidHorizontal both of CrossSectionPositions attributes which are lists of IfcAxis2PlacementLinear. The implementation of each class used its own bespoke mapping of IfcAxis2PlacementLinear, which were identical to each other and slightly different than IfcAxis2PlacementLinear. Now the two sectioned classes use the one and only mapping for IfcAxis2PlacementLinear
