perf_hooks: add HttpRequest statistics monitoring #28445

```js
const { PerformanceObserver, performance } = require('perf_hooks');
const http = require('http');

const obs = new PerformanceObserver((items) => {
  const entry = items.getEntries()[0];
  console.log(entry.name, entry.duration);
});
obs.observe({ entryTypes: ['http'] });

const server = http.Server(function(req, res) {
  server.close();
  res.writeHead(200);
  res.end('hello world\n');
});

server.listen(0, function() {
  const req = http.request({
    port: this.address().port,
    path: '/',
    method: 'POST'
  }).end();
});
```
