Merge bitcoin/bitcoin#32837: depends: fix libevent _WIN32_WINNT usage

f5647c6c5a depends: fix libevent _WIN32_WINNT usage (fanquake)

Pull request description:

  Starting with version 13.x, the mingw headers will define the value of
  `NTDDI_VERSION`, based on the value of `_WIN32_WINNT`, if that version is <
  Windows 10. Given that libevent was undefining our `_WIN32_WINNT`, and
  redefining it to a value < Windows 10 (`0x0501`), `NTDDI_VERSION` was also
  being defined to that value, leading to functions not being exposed in
  the mingw-w64 headers; see here: 9c2668ef77/mingw-w64-headers/include/iphlpapi.h (L36-L41).

  Imports a commit from usptream ([a14ff91254f40cf36e0fee199e26fb11260fab49](a14ff91254)).

  Fixes #32707.

+move _WIN32_WINNT defintions before first #include
+
+_WIN32_WINNT and WIN32_LEAN_AND_MEAN need to be defined
+before the windows.h is included for the first time.
+Avoid the confusion of indirect #include by defining
+before any.
