jijinbei 4418ba3204 shim: share flg(SmBoolean), put_ivl and put_mat through sc_sm.h 
Adds the three helpers to sc_sm.h, copied from the per-shim copies they
replace, and switches 19 shims to the shared flg/put_mat/put_vec/put_ivl/st/
put_dom. Shims touched by open PRs are left alone.

// difftest shim for unit `curve.hyperbola`.
// Wraps upstream SmHyperbola (source/SMLib/inc/SmHyperbola.h, source/SMLib/src/SmHyperbola.cpp):
// the constructor (and so MakeNurb), operator==, AdjustSTEPInterval, STEPInversion, Copy,
// EvaluateSTEP, GlobalPointSolveSTEP, IsBounded, IsAnalytic, IsArc, GetSTEPInterval,
// GetMaxAnalyticDomain, ReverseParameterization, Transform, ReadFromDB, IsKindOf and the type
// strings.
//
// One entry point, sc_curve_hyperbola_eval(op, in, n_in, out, cap, out_len). Layouts are
// documented in crates/solidcore-ffi/src/units/curve_hyperbola.rs, which validates every input.
// Member ops start with a hyperbola block `O[3] X[3] Y[3] dmin dmax a b dim`
// (`new (ctx) SmHyperbola(O, X, Y, SmExtent1d(dmin, dmax), a, b, dim, &ctx)`). `out` receives the
// op status (0 = SM_SUCCESS, else the SmStatus value), the op's outputs, then the state of `this`
// (member ops) or of the curve read (ReadDb). A state is
// `O[3] X[3] Y[3] dmin dmax a b dim oob borrowed knot_type form has_nurb [n p m cpts knots]`.
