Pre-built binary for windows-arm64

[izaakschroeder]

It looks like there's a target for windows-x64 here:

skia-canvas/.github/workflows/build.yml

Line 128 in f125bcb

windows-x86:

but nothing for windows-arm64 😢 This would be a major benefit to those of us suffering with a Apple Silicon desktop that has to use virtualized (arm64) Windows for development 😅

If this is easy to add that would be great 🎉 If not… I can probably find some kind of manual build to do following the README but it would be amazing to npm install and have it just work™.

The limiting factor at the moment is the lack of Arm-based runners on GitHub Workflows (which is how binaries are currently built). They've been 'just around the corner' for years at this point and will some day become available to open source projects.

In the meantime the only way to get Windows Arm support would be to modify the windows-x64 recipe that you found to cross-compile the library for Arm (despite the host machine running on x64). I'm not nearly knowledgeable enough about Windows to know how to get that working (especially in conjunction with llvm & rustup) but if anyone who is would like to get the ball rolling, I'd love to add support for it.
