Add AMD/ROCM support to ML.NET

Issue originally reported in Model Builder repo by @Selbyl

dotnet/machinelearning-modelbuilder#2764

ROCM is being supported more on Windows recently.

I know AMD isn't as popular as Nvidia for AI, but is ther any future of updating ml.net to support PyTorch with ROCM?

In order for ML.NET to support this, TorchSharp and/or ONNX would have to support it. Currently, ONNX does through the Execution Providers.

However, they don't publish a NuGet similar to DirectML and OpenVINO.

In order to get this working in ML.NET and even then, this would only work for inference scenarios using ONNX Execution Providers, you'd need to:

• Build ROCM from source and copy the C/C++ binaries to your .NET application similar to this process. https://github.com/dotnet/machinelearning/issues/6264#issuecomment-1200507455

Closing this issue for now.
