bpo-45548: Remove _math.c workarounds for pre-C99 libm (GH-29179) 
The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible
``libm`` and no longer ship with workarounds for missing acosh, asinh,
expm1, and log1p functions.

The changeset also removes ``_math.c`` and moves the last remaining
workaround into ``_math.h``. This simplifies static builds with
``Modules/Setup`` and resolves symbol conflicts.

bf9655854b Issue #28256: Cleanup _math.c 
Only define fallback implementations when needed. It avoids producing deadcode
when the system provides required math functions.
