LibreSSL headers emit this warning because we included `wincrypt.h`
before them. We have to include `wincrypt.h` before OpenSSL headers
to avoid symbol collisions when using other forks. LibreSSL 3.8.2+
offers a macro to silence its warnings to avoid this issue. This patch
sets it.
This allows to stop setting this macro in curl-for-win builds.
Warnings seen with MinGW with cmake non-unity (also unity batch=30):
