Steps to reproduce:

Compile OpenSSL 3.0 on Windows.
use get_externals.bat to download Python external requirements on Windows.
Overwrite OpenSSL 1.1.1m in externals with your OpenSSL 3.0 build.

Expected behavior:
Python will build against OpenSSL 3.0

Actual behavior:
Build fails with missing DLLs.

Further information:

For OpenSSL 3.0 builds, the first suffix for libcrypto and libssl is -3, not -1_1.
For x86_64 builds, there's also an -x64 suffix to distinguish from x86 builds.

I have a openssl.props modified file at:
https://github.com/GAM-team/actions-hello-world/blob/master/openssl.props

which I've overwritten the existing:
https://github.com/python/cpython/blob/main/PCbuild/openssl.props#L13

file with and then succesfully compiled against OpenSSL 3.0. However I'm not certain if or where the logic should exist to detect OpenSSL 3.0 DLLs instead of 1.1.

OpenSSL 3.0 support is still experimental and incomplete. 3.10 is definitely out of scope. 3.11 might be feasible if somebody puts in the work.

This is pretty much done via PRs connected to gh-99079.
