Add support for webassembly

See original GitHub issue

When trying to run on webassembly I get the following exception:

If you enable that msbuild setting then it sets up some machinery to use web workers for running additional ‘threads’.

The first problem with this with Avalonia is that you need WASM builds of SkiaSharp and HarfBuzz that have been built with some extra threading options, and it looks like that’s still only available in the preview builds. (https://github.com/mono/SkiaSharp/issues/2285)

I just gave it a go with a build that I changed to use the preview Skia build, and it build and ran (my top level UI displays in the browser, and the browser dev tools show the workers being present), but then it hit other problems before getting to the AvaloniaEdit parts… I’ll try to test it with a more minimal test later

Does .net7 support threads by default in wasm? or not yet?
