Merge bitcoin/bitcoin#25422: build: globally define NOMINMAX when building with mingw-w64

58a9601dffa6d9b3b881a476169458787d382919 build: globally define NOMINMAX (fanquake)

Pull request description:

  Define (and document) `NOMINMAX` once, rather than across multiple
  source files.

  Defining this prevents the definition of min/max macros when using
  mingw-w64, which may conflict with unprefixed std::min/max usage. While
  that might not be the case for us, we'd always prefer to use the standard
  library in any case.

  For example:
  https://github.com/mingw-w64/mingw-w64/blob/73cadc06c62c6af5faf76f64ef08e684b48de48c/mingw-w64-headers/include/ntdef.h#L289-L300

  Note that we already define NOMINMAX globally when building with MSVC.

  Guix Build (arm64):
