feat(ext/web): resourceForReadableStream (#20180)
Extracted from fast streams work.
This is a resource wrapper for `ReadableStream`, allowing us to treat
all `ReadableStream` instances as resources, and remove special paths in
both `fetch` and `serve`.
Performance with a ReadableStream response yields ~18% improvement:
```
return new Response(new ReadableStream({
start(controller) {
controller.enqueue(new Uint8Array([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]));
controller.close();
}
})
```
