feat(turbopack): add support for parallel routes and route interception

[ForsakenHarmony]

What?

We have to walk the directory tree recursively for every page (instead of once) to get the correct loaderTree.

With this PR we walk the directory tree and for every page.(js,jsx,ts,tsx) (entrypoint) we find we walk it again to get the loader tree for that page

Closes WEB-1868
Closes WEB-1609
