[Feature Request] Add 32-bit support for onnxruntime-node

### Describe the feature request

Add 32-bit binaries to`onnxruntime-node`, as they are currently unsupported.

### Describe scenario use case

The Copilot extension relies on `onnxruntime-node`, and we have reports of users having activation issues, with the extension failing to load a file at the following path:

```
Activating extension 'GitHub.copilot' failed: Cannot find module '../bin/napi-v3/win32/ia32/onnxruntime_binding.node'

Require stack:
- c:\Users\\.vscode\extensions\github.copilot-1.79.10634\dist\node_modules\onnxruntime-node\dist\binding.js
```

Start by tracing the reported onnxruntime-node dist/binding.js path and the missing win32/ia32/onnxruntime_binding.node binary. Determine how 32-bit binaries are produced and packaged, then verify that the reported Copilot activation failure no longer occurs for 32-bit Windows users.
