* Move nodejs ptah module usage to next-server, keep base-server and web-server headless for `'path'`
* Use a native module `path` for nodejs runtime and `path` polyfill for edge runtime
(#31506 for context)
This PR implements the minimum viable web server on top of the Next.js base server, and integrates it into our middleware (edge) SSR runtime to handle all the requests.
This also addresses problems like missing dynamic routes support in our current handler.
Note that this is the initial implementation with the assumption that the web server is running under minimal mode. Also later we can refactor the `__server_context` environment to properly passing the context via the constructor or methods.
Part of #31506, this PR moves the code of middleware handling from the base server to the node server.

This fixes revalidation not occurring correctly when `notFound: true` is returned during build, additional tests have been added to ensure this is working correctly for dynamic and non-dynamic pages returning `notFound: true` during build and then revalidating afterwards.

Fixes: https://github.com/vercel/next.js/issues/21453
This allows the user to adjust the LRU cache size according to the
application need:
- optimize the cache size based on average page HTML & JSON size
- disable the memory cache by setting the size to 0
The hard-coded default of 50MB has been moved from the code to the
default configuration object.
Fixes#21535

@tommarshall has done us a huge favor with his PR https://github.com/vercel/next.js/pull/24807 which outlines exactly the issue and a pragmatic solution.
I'm not trying to "steal their work", however, the PR seems to have been stuck for some months. I think there's huge value in this for myself and others as essentially **ISR is broken** for people running Next.js at scale 😱
This PR has cherry-picked @tommarshall's fine fix and added some integrations tests around page revalidation and the edge case when the cache size is exhausted.
✏️ Edits are enabled, so feel free great Vercel staff and other maintainers to improve my bad tests or surrounding code 🙇

Make the typing for `IncrementalCache` more explicit. With streaming, we’ll want to stream page data as well as HTML. This is a bit complicated now because we’re overloading `pageData` for both redirects and pages.
This PR makes the different types explicit. With streaming, the data for redirects is synchronously available, while the data for pages will become a stream.
A follow up PR will add a “stream through” cache in front of `IncrementalCache`
