Petru Conduraru e333c1c100 ifcgeom: build the swept-area directrix from the offset curve far from origin (#4848) ...

IfcSurfaceCurveSweptAreaSolid regressed in 0.8 for geometry far from the
origin (for example parapets on a georeferenced building), which went
missing or glitched.

The kernel offsets the directrix toward the origin when it is far away
(mean.norm() > 1e2), storing the offset copy in a local curve variable and
setting applied_temporary_offset so the finished solid is translated back by
+mean. But the wire was still built from scs->curve, the un-offset original,
so the offset never took effect and the result was translated by +mean from
its correct location. Build the wire from curve instead. When no offset is
applied curve aliases scs->curve, so near-origin geometry is unchanged.
