Add support for dynamic `import()`s on the server-side (#3193)
This PR separates Turbopack's `runtime.js` into two:
- the Browser/DOM implementation, which uses `<script>` and `<link>`
tags for dynamically loading chunks;
- the Node.js/CommonJS implementation, which uses `require` instead.
~~The two runtimes share a lot of code, but I'm not sure what's the best
approach for sharing this logic, or even if we should, so for now they
are two separate entities.~~
The shared code between the two runtimes is now in a separate file to
avoid duplication.
