Fix local worker runtime freezing

[frandiox]

Closes #1720
Closes #1784

We were not handling workerd log streams properly because we ingest the logs using the inspector protocol instead.
These streams were probably reaching their internal buffer limit and workerd freezes after that.

🎩 To test this, h2 dev in skeleton template, open the home page in the browser and open the Network tab with the console below (ESC). Run the following code in the console without the changes of this PR, then apply these changes and try again:

for (let i = 0; i < 1000; i++) {
  const res = await fetch('http://localhost:3000/search');
  const result = await res.text()
  console.log(i);
}

Without the changes in this PR, it will freeze after ~90 requests.
