Variable templates for mathematical constants.
Single API for toy::math::FractionalConstantType: float, double, long double, and toy::math::fixed. Values forward to std::numbers for built-in floating-point types and to std::numbers specializations for toy::math::fixed (see math/fixed_std_extension.hpp).
