Support Windows for ARM64

[carlo-bramini]

Feature Description

I'm wondering what you think about releasing a version of Mixxx for Windows for ARM64, compiled as native ARM64 application.
Since you are using VS2022 and VCPKG, creating executable for Woa64 is as easy as doing the one for Win64: changing the target into CMake and VCPKG from x64 to arm64 should do the whole job, without any change to the source codes of the application.

Not sure how many users with an arm windows are out there. So I may raise our CO2 footprint without a real benefit.
But feel free to give it a try. The issue is that we need to cross compile on the GitHub workflow runners.

Counterargument: People running mixxx on ARM windows have to use an emulator that has overhead and thus also wastes energy... As a compromise, the windows ARM CI could be run less often (once a week instead of on every PR).
