feat(efloat): implement mathematical classification library (#1124)

* feat(efloat): implement mathematical classification library (#1109)

Implement fpclassify(), isfinite(), isinf(), isnan(), isnormal(), isdenorm(), and signbit()
inside math/classify.hpp, fully complying with standard <cmath> behavior and the
IEEE-754 standard.

Register math/classify.hpp inside our master efloat mathlib.hpp header.

Create classify.cpp inside elastic/efloat/math/ to verify all classification functions against
extreme values (+/-0.0, QuietNaN, +/-Inf, and Normal values).

Resolves #1109
Relates to parent Issue #1092, Epic #1101

* fix(efloat): resolve CodeRabbit review comments on classification

Implement sw::universal::iszero(const efloat<nlimbs>&) noexcept free function
inside math/classify.hpp, delegating to x.iszero(). This completes the standard
classification predicates.

Add iszero() regression tests in classify.cpp.
