### Description

In Next.js with webpack we have a feature to inline `typeof window` in
server/client environments. That allows e.g.

```
"use client"
if(typeof window === 'undefined') {
  import('server-only-package')
}
```

Today with Turbopack above code causes `server-only-package` to still be
loaded in the browser compilation. Which causes issues like
https://github.com/vercel/next.js/issues/66058 where the `if`/`else`
condition is used to use different modules for server and client.

This change is required to pass the test in
https://github.com/vercel/next.js/issues/66058

Pushing up the Next.js changes in that PR.
