build(windows): cross compile for arm

[ReenigneArcher]

Description

This PR attempts to cross compile Windows for arm. This is unlikely to work as is.

Todo:

• This currently won't work because the wrong toolchain is installed, and there are no packages available for the cross compilers? https://www.msys2.org/wiki/MSYS2-introduction/#subsystems
• Cross compile build-deps for arm
• Some dependencies not available in clang-aarch64 environment

The problem is that the clangarm64 toolchain don't just create ARM64 binaries, they are ARM64 binaries. We need an ARM64 runner to run the build.

I figured that was the problem. I think this might be able to work on one of the new macos runners (arm), and then cross cross compile for Windows with mingw64.
