Development: Don't import app-router / hot-reloader through next/link in application code (#83656)
## What?
Removes imports from the app-ssr layer that cause transitive
dependencies to be included during compilation in development.
For the trace that I received from an application there was quite a bit
of overhead for them because of this issue.
Trace:
next.js
