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.

When emitting the client components entry from server compiler, merging
app internal entry into main-app to avoid duplicated chunks like react
are generated in both sides

Creates a root layout if it is missing in DEV when building the page in
`next-app-loader`. If the page is in a route group, the layout will be
created there. Otherwise it will create a layout directly under `/app`.
Breaks the build if a page is found that's missing a root layout.

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
