This PR introduces an optimization to `set_response` to reduce the
overhead for responses with a payload size less than 64 bytes.
Performance gains are more noticeable when `is_request_compressible`
enters the slow path, ie: `-H 'Accept-Encoding: unknown'`
### Benchmarks
```js
Deno.serve({ port: 3000 }, () => new Response("hello"));
```
```
wrk -d 10s --latency -H 'Accept-Encoding: slow' http://127.0.0.1:3000
```
