Skips additional production-only tests.
Follow-up to #56089.
In this PR I went through all of `test/integration` looking for `nextBuild(` and added the skipping logic.
This PR merges the app renderer worker into the router process. This
improves the memory overhead mostly.
There're future work to do to get rid of the IPC server for router and
app renderer, as they're now merged in one process.
Fixes NEXT-1492
- Enables excludeDefaultMomentLocales by default
- Adds distDir cleaning (See RFC #6009)
- Adds support for `PORT`
- Removes `router.events` from the server-side router as it should not be used server-side (long-standing todo that is potentially breaking). Note that it's still available as `Router.events` (import Router from 'next/router') and with `useRouter` in `useEffect`. Using it with `useEffect` is the correct way and I've updated the upgrading guide to reflect that
- Added webpack 5 to the upgrading guide
- Removed `Head.rewind` as it's been a no-op since Next.js 9.5 and can now be safely removed from user code
