[msbuild/dotnet] Add support for compressed xcframeworks in binding p…

…rojects and as NativeReference items. Fixes #21294.

Now it's possible to reference a compressed xcframework like this:

```xml
<NativeReference Include="path/to/myframework.xcframework.zip" />
```

This makes it easier to work with xcframeworks on Windows, because
xcframeworks can contain symlinks, and by zipping them up the whole symlink
problem is avoided.

Turns out there's already a NuGet that adds a .xcframework.zip file as a
NativeReference (Microsoft.ML.OnnxRuntime), so this makes that NuGet work.

Fixes #21294.
Fixes #21450.
