Add Meson to CMaNGOS

[insunaa]

🍰 Pullrequest

This PR adds the Meson Build System to CMaNGOS. Works great with Linux, OK with MacOS and barely works with Windows (but does work).
I seem to be the only one who sees value in this, so if nobody else can be convinced to switch to a simpler build system than CMake then close the PR again.

Todo / Checklist

• Improve Windows Support

As you said it, barely works on windows. I see the issue mainly that I would then be responsible to help with maintaining it works :D And also, I have never seen it before so that means its not as well adopted.

All the big Linux OSS projects use Meson. Gnome does, Systemd does and quite a few others too https://mesonbuild.com/Users.html

Also I've been maintaining a meson fork of tbc for months now, it doesn't need changes unless files are added or removed

Debian Unstable with Meson + Ninja (the "derp" dependency was just added as a proof of concept. We redistribute bzip2 in dep/src/bzip2 but it's a version from 2014 I think, like this I can just pull in the latest bzip2 directly from upstream

I pushed openssl 3.0 support commit right away, thanks.
