[Feature Request] Get GPT4All to work with onnxruntime

### Describe the feature request

I would like to run this model with onnxruntime:

[GPT4all ](https://huggingface.co/Sosaka/GPT4All-7B-4bit-ggml)

I don't believe you can currently successfully convert this into an onnx runtime and run it with onnxruntime.

If I am wrong please describe the process. Thanks.

If not, can you suggest an alternative framework other than onnxruntime to run this with c#/DirectML?

### Describe scenario use case

To run this model and similar models.

Start by investigating whether the linked GPT4All-7B-4bit-ggml model can be converted and run with ONNX Runtime. Review the repository’s existing C#/DirectML support and model-conversion guidance, if available. Done means a documented working path, or a confirmed limitation with an alternative framework.
