math: Simplify and optimize modff implementation
Refactor the generic implementation to use math_config.h definitions,
and add an alternative one if the ABI supports truncf instructions
(gated through math-use-builtins-trunc.h).
The generic implementation generates similar code for x86_64, while
the optimization path aarch64 (where truncf is supported as a builtin)
through frintz), the improvements are:
