Turbopack: Always use blob: URLs for assets in middleware (#71471)
Closes PACK-3304
This was originally done in https://github.com/vercel/next.js/pull/63209
But I don't think this is correct.
Without this change, the added test fails with
```
Error: failed to pipe response

input: '/_next/static/media/noto-sans-v27-latin-regular.7e1666d1.ttf',
code: 'ERR_INVALID_URL'
}
}
```
(because the `blob:` prefix is missing for the font static URL)
