Brett Lawson e0a1c10904 surface: keep a plane's or extrusion's made NURB on the surface, as GetOrCreateGwNurbPointer 
BSplineSurface stores its NURB in a NurbSlot (a OnceLock) that read-only
queries can fill once from &self, as upstream's GetOrCreateGwNurbPointer
keeps a NURB made through a const_cast. Plane::base_with_nurb and
SurfOfExtrusion::base_with_nurb now make a missing NURB and keep it, so
IntersectWithPlane's has-NURB test, ToggleSwapUVBit, operator== and copies
see it. Plane::copy makes the source's NURB first and the source keeps it,
as the SmBSplineSurface copy constructor. Surface::kind_with_nurb fills the
extrusion's slot instead of the side memo; cone, sphere, torus and
revolution keep the whole-kind memo (their MakeNurb also rebuilds the polar
converter).

surface.plane_p1 drops its workarounds: the shim asks const queries of the
plane itself instead of a side-free copy, the state records whether the
plane holds its NURB, and ToggleSwapUVBit / operator== are generated
anywhere in a program.

// difftest shim for unit `surface.plane_p1`: the SmPlane members owned by the unit
// (source/SMLib/src/SmPlane.cpp, source/SMLib/inc/SmPlane.h), called on SmPlane objects (virtual
// dispatch is upstream's), plus the inherited SmBSplineSurface members the port re-dispatches for
// planes (GetNaturalUVDomain, GetMaxAnalyticDomain, IsBilinear, IsParallelToVector, GetDegree,
// GetNumberControlPoints, Reverse, SwapUV).
//
// One entry point, sc_surface_plane_p1_run(in, n_in, out, cap, out_len). `in` is a program: a
// plane block (plane A), the op count, then the ops; layouts are documented in
// crates/solidcore-ffi/src/units/surface_plane_p1.rs. Every read is bounds checked here (a bad
// program is SC_ERR_ARG). `out` receives `make_status`, then per op `op status [values]` (values
// only when the status is 0), then the state of A. A failed plane block ends the record after
// its status.
//
// Const queries that make the NURB of a plane without one (GetNaturalUVDomain and friends, the
// copy constructor) are asked of the plane itself: upstream makes the NURB then and keeps it
// (GetOrCreateGwNurbPointer through a const_cast), and the port models that, so the record shows
// when it is made. The state prints whether the plane has its NURB, then that NURB (made first
// when missing, as GetOrCreateGwNurbPointer does).
