Minimal example of using ONNX Runtime with WebGPU in Node.js

Setup steps

1. build onnxruntime with WebGPU

   use branch fs-eire/webgpu-ep

   in the root folder of onnxruntime source code, run the following command:

   build --config Debug --use_webgpu --build_nodejs --skip_tests
   

2. make a symbol link to the root folder of ONNX Runtime source code. (assume the source code is in C:\code\onnxruntime)

   mklink /D /J onnxruntime C:\code\onnxruntime
   

3. run npm install in the root folder of this project.

4. prepare model.

   md models\microsoft
   cd models\microsoft
   git clone https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx-web
   

   if not working, try this link.

5. run node .\main.js to run the sample code.
