Update .NET libraries and runtime dependencies

[ericstj]

Update to the latest libraries for all dependencies of ML.NET that come from dotnet/runtime (and prior) repositories.

I noticed that the dependency on PlatformAbstractions.RuntimeEnvironment.GetRuntimeIdentifier(); was broken because DependencyModel stopped referencing PlatformAbstractions. I was able to fix this by refactoring that code to use https://docs.microsoft.com/en-us/dotnet/api/system.runtime.loader.assemblydependencyresolver?view=net-6.0 which exists since .NETCore 3.0 and calls in to the host to probe for deps-file-defined dependencies. I've tested that this works with both local runtime dependencies and nuget cache probing.

/// Third: The library as resolved via the default DependencyContext, in the default nuget package cache folder.

This comment should probably be updated.

I haven't yet fixed the tests here, needed to get some fresh results.
