Add experimental support for Windows ARM64

[dpaoliello]

Adds experimental support for Windows ARM64:

• Add instructions on how to cross-compile for Windows ARM64.
• Add sections to config.toml.
• Update to version of maybenot that uses newer version of ring that supports Windows ARM64.
• Ran cargo update.
• Updated build scripts to support Windows ARM64 or be architecture agnostic.
• Modified exception logging to support ARM64 context.
• Added ARM64 configs to C++ projects.

NOTE: WireGuard is working, but OpenVPN is not.

Assuming that the host is x64 won't work on arm. This might deserve a comment at the very least.

[dpaoliello]

@dlon this PR is not yet ready for review: first we need the prebuilt aarch64-pc-windows-msvc binaries added to the dist-assets/binaries submodule. I'm assuming that's something that you or someone else from Mullvad needs to do so that the binaries are built in a trusted way (and, at the very least, the driver needs to be signed).

[dlon]

@dpaoliello The binaries are available on the arm64-binaries branch of mullvadvpn-app-binaries (but not yet merged, and apisocks5 is missing). So feel free to make sure that this PR is ready for review.

Working for me locally:

@dpaoliello It works great using Wireguard! We can get OpenVPN to work as well by building talpid_openvpn_plugin.dll for x64 instead of arm. I've added the arm build of wintun.dll to the branch in the binaries submodule.

Yep, using x64 talpid_openvpn_plugin.dll worked.

The alternative is to get an ARM64 openvpn.exe - it looks like the last successful build of Mullvad's openvpn repo did include ARM64 Windows, but the artifacts are now expired: https://github.com/mullvad/openvpn/actions/runs/7058997763

[dlon]

We don't think it makes sense to block this PR on an ARM64 openvpn build. Let's include an x64 build of talpid_openvpn_plugin.dll and we'll take of it later.

We currently cross-compile openvpn using mingw on Linux, which can't target arm, and our branch doesn't even compile with MSVC. We'll likely switch soon, though.

Done

The _x64 suffix is missing now from the function in test/scripts/test-utils.sh.

I believe $version_suffix should come before _x64 | _arm64.

[dlon]

Fixed the issues above and also added apisocks5.exe.
