[PATCH 1/2] benchtests: Add fmaximum and fminimum family benchmarks

[Julian Zhu]

Add inputs for the C23 fmaximum, fminimum, fmaximum_num and fminimum_num families in both float and double precision.  Cover finite values, infinities, quiet NaNs and signaling NaNs, and disable compiler builtins so the benchmarks exercise libc.
