http.createServer should accept suspend function

[DHosseiny]

In http.createServer(RequestListener), RequestListener should be a suspend function. In traditional Js, we can set this function to async and call await inside of it, But without RequestListener being suspend we can not call Promise<T>.await()

[DHosseiny]

async function myAsync() {
  return 'Hello world'
}

http.createServer(async function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.write(await myAsync());
  res.end();
}).listen(3000);

This is working in js.
