In `v14.0.2-canary.1` users started noticing more memory errors
especially with many edge runtime configured pages. After investigation
it seems this can be related to the additional transpiling we configured
in https://github.com/vercel/next.js/pull/59569 and
https://github.com/vercel/next.js/pull/57784
To help alleviate this we are updating the default swc loader to have an
additional check to see if no special features such as `next/font`,
`next/dynamic`, or `use server/client` directives are present and then
no-oping in the loader to avoid additional overhead for a majority of
modules.
For monitoring regressions our `stats-app` has been updated with
repeated edge-ssr routes to hopefully help us keep an eye on memory or
cache size issues.

For app edge SSR, we don't need any internal pages for it since it's
handled by app-renderer. This results around reducing 20KB from app edge
SSR
# Changes
* Strip those internal pages modules when it's in app edge SSR
* Minimize edge SSR chunk to see the tree-shake result
* Add bundle analyzer with switcher in stats-app for testing. Using
`TEST_ANAYLYSE=1` to build stats-app for testing
since we no longer have a single compiler for browser & edge, we can enable
source map generation by default for all edge functions. This would make it
much easier to debug and understand what's happening when deploying to prod
as the log statements will show us the actual code location instead of post
bundling and minified location.
This also removes the experimental flag as it's not needed anymore.
This removes the config for the `commons` chunk.
I think the idea was that modules are that in all pages are put into a `commons` chunk, but that breaks when next/dynamic comes into play, which also creates chunks. So the `totalPages` condition is broken and could lead to too many modules placed into the commons chunk.
Example: 2 pages, each has one next/dynamic. Both on demand chunks include module A. page 1 includes module B and next/dynamic on page 2 includes module B. A and B are placed into commons. commonjs chunk is loaded in page 1 and both next/dynamic. Page 1 would load module A even while it doesn't need it.

* Enable webpack 5 by default for all apps
Still provides a way to opt-out using `webpack5: false` in next.config.js. Also throws an error for `future.webpack5`.

This PR removes the modern mode experiment because:
- It does not yield meaningful bundle size wins when compared to other initiatives we've taken
- It's not compatible with webpack 5 (which we're upgrading to)
- It's currently broken and causes most apps to malfunction
- There's no champion currently owning the experiment
We can re-introduce this in the future when we'd like to make it a default for all Next.js apps.
Note: **Next.js still supports Differential Loading (`nomodule`) and does it by default.** This PR strictly removes the experimental modern _syntax_, and does not disable our existing modern/legacy polyfilling.

This removes remaining references to `granularChunks` in configs, error messages, and comments.
Also removed the `process.env.__NEXT_GRANULAR_CHUNKS` value.
