M1 Support

[christophwille]

See https://github.com/actions/virtual-environments/issues/2187

We need GitHub Actions support (local building https://github.com/icsharpcode/AvaloniaILSpy/blob/master/ILSpy/ILSpy.csproj#L10 needs to be adjusted, but first #82 needs to be merged because M1 support is in .NET 6.0)

I just ordered a M1 MacBook, I'll pick this up next month

I too should get an MBA soon for testing; could you take a look at #82 before? Should be innocous enough (binaries work nicely on Windows)

I have a 64 bit macbook pro from 2015 I can test it on. But I do not see why it would not work.

Also for M1 I think they are ARM64 only as well with apple wanting to basically eliminate normal x64 entirely eventually.

And it works on my Mac. 👌

I have merged my PR #82 - I got my MBA M1 for testing now.

Edit: dotnet run doesn't like M1 out of the gate

I added the RID "osx-arm64" - that didn't change a thing; then in ILSpy.csproj I started adding SkiaSharp to override Avalonia's default version - each version https://www.nuget.org/packages/SkiaSharp/ gave a more detailled error message until I hit the one for libHarfBuzzSharp on version 2.88.0-preview.155 which seems to have been reported on SkiaSharp repo:

https://github.com/mono/SkiaSharp/issues/1829

Given that I am not an expert on any of those things (code signing on Apple, Skia or Avalonia) this is the beginning of investigations for somebody else.
