bpo-45440: Require math.h isinf() to build (GH-28894)
Building Python now requires a C99 <math.h> header file providing
isinf(), isnan() and isfinite() functions.
Remove the Py_FORCE_DOUBLE() macro. It was used by the
Py_IS_INFINITY() macro.
Changes:
* Remove Py_IS_NAN(), Py_IS_INFINITY() and Py_IS_FINITE()
in PC/pyconfig.h.
* Remove the _Py_force_double() function.
* configure no longer checks if math.h defines isinf(), isnan() and
isfinite().
