Support for Windows arm64 versions

[SuavePirate]

Similar to how OSX supports legacy x86 and new arm64 versions of apps, Windows has also released a new arm64 version of the platform. However, it does not seem like there is a way to separate these builds for download and updates within nuts like there is in osx.

For example, in OSX we can provide the architecture we need like:
https://my-update-server.com/update/osx_arm64/:version
https://my-update-server.com/update/osx_x86/:version

But when trying to do the same for win32 there is no arm64 support:
https://my-update-server.com/update/win_arm64/:version - nothing happens
https://my-update-server.com/update/win_x86/:version - works
