[js/web] allow import .mjs/.wasm file (#23487)

### Description

Allow importing the `.mjs` and `.wasm` files.

when using Vite, this enables web app to consume ORT-web for simplify
the setup:
   ```js
   import * as ort from 'onnxruntime-web';

   import wasmFileUrl from 'onnxruntime-web/.wasm?url';
   ort.env.wasm.wasmPaths = { wasm: wasmFileUrl };
