Support Windows arm64 via the win32-x64 variant

[chadlwilson]

Currently if you try and install this on Windows 11 Arm64 no native variant is installed, and at runtime you will get

[webpack-cli] Error: Embedded Dart Sass couldn't find the embedded compiler executable. Please make sure the optional dependency sass-embedded-win32-arm64 is installed in node_modules.

I've successfully used Dart Sass (native x64) via Ruby on Windows via emulation (ruby host uses this logic) which is still much faster than old variants.

Short of a full arm64 win32 compile of Dart Sass, could this project be changed to fall back to install and expect win32-x64 when it otherwise would desire win32-arm64? Would such a PR be considered?

Yeah, if that works we'd be happy to take a PR for it.

Cool, thanks! I wonder if this would this be a good use of time in the first place, as I understand the Dart SDK has Windows arm64 support. Having said that, perhaps this isn't something the dart-sass team would be comfortable building and supporting at this stage.

Dart support for Windows ARM64 is still experimental. If this is a high priority for you, we'd be happy to take a PR to use x64 instead until it's stable and we can release proper ARM64 support.

Oh, wow, thanks @ntkme and 👋
