Bug 280715: math/py-numpy: remove clang error condition in distutils check
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280715
--- Description ---
numpy has a C source file in their distutils checks, which is supposed
to check for AVX512FP16, but for apparently historical reasons, it has:
/* clang has a bug regarding our spr coode, see gh-23730. */
#if __clang__
#error
#endif
Since clang 19 now supports the -mavx512fp16 flag, other ports such as
science/py-scipy (which depend on numpy) then bomb out in their
configure scripts with:

I have tried clang 15 through 19 on cpu_avx512_spr.c with the #error
removed, and none of them crashed or otherwise got an error. So I think
we should simply remove the whole #if / #endif part.
Also bump the portrevision, to force dependencies to configure against
the new cpu_avx512_spr.c file.
