Stacked on #30906. Injects the Flight Client into the DevTools hook if it `supportsFlight`. This only injects in DEV. We could inject it in prod too but so far the only feature this exposes is only available in DEV anyway. I also only call `injectIntoDevTools` in the browser builds since we don't really support DevTools on the server anyway. The main purpose of this for now is so that DevTools can track the Server Component owner of replayed logs. This lets us add owner stacks where `console.createTask` is not natively supported (like Firefox). It also lets us associate the log with the Server Component in the Component tree #30905.
