Adhemerval Zanella bccb0648ea math: Use tanf from CORE-MATH 
The CORE-MATH implementation is correctly rounded (for any rounding mode)
and shows better performance to the generic tanf.

The code was adapted to glibc style, to use the definition of
math_config.h, to remove errno handling, and to use a generic
128 bit routine for ABIs that do not support it natively.

Benchtest on x64_64 (Ryzen 9 5900X, gcc 14.2.1), aarch64 (neoverse1,
gcc 13.2.1), and powerpc (POWER10, gcc 13.2.1):
