Adhemerval Zanella d846f4c12d math: Use lgammaf from CORE-MATH
The CORE-MATH implementation is correctly rounded (for any rounding mode)
and shows better performance to the generic lgammaf.

The code was adapted to glibc style, to use the definition of
math_config.h, to remove errno handling, to use math_narrow_eval
on overflow usage, and to adapt to make it reentrant.

Benchtest on x64_64 (Ryzen 9 5900X, gcc 14.2.1), aarch64 (M1,
gcc 13.2.1), and powerpc (POWER10, gcc 13.2.1):
