This PR exposes internal injection point to specify custom binary /
bindings for the turbopack. It doesn't affect any existing native
bindings (swc), but only allows to run custom turbopack
(`turbo.startDev`) if specified.
The changes are mostly for the internal dev / testing iteration purpose.
Currently, the workflow to test new turbopack changes in next.js is
- update next-swc's cargo to point to specific changes in turbopack
- rebuild, specify next.js to use local binary
This requires additional build times (turbopack build cannot be used,
have to rebuild next-swc napi bindings) as well as if we'd like to try
some changes on the CI between next.js canary + latest turbopack,
integration gets bit tricky. 2 env variable is exposed for the purpose -
`__INTERNAL_CUSTOM_TURBOPACK_BINARY` stands for the executable binary
(next-dev) can be built in turbopack,
`__INTERNAL_CUSTOM_TURBOPACK_BINDINGS` stands for the custom napi
bindings if needed. Both are strictly internal as name implies. There
won't be any documentation, no semver guarantee or else. Current plan is
to execute some subset of next.js test on turbopack PRs with these
entrypoints.
Feature / security wise these are mostly harmless I believe - this is
devserver usually don't run on CI, and trying to print out warning if
flag is enabled.

One potential risk is ESM dependencies that can't be bundled will cause
a build error. This also means that the `esmExternals` configuration
will be affected.

Cases like `next/link` and `next/router` imports are not alias since
they're not matching the existing alias pattern setting for edge
runtime, which causes router-context being bundled twice (both with cjs
and esm) into edge worker bundle.
so we resolve their paths and alias them to esm bundle for webpack
bundling.
Other minor changes:
* update `require` calls to `import` expressions in edge ssr loaders
* remove client layer for apps without `appDir` enabled
* export `type` for ts typings in next/image to avoid alias to break
resolving

* Use eager `import()` to load page/layout to avoid esm module resolution error, eager is to make sure all the sub resources like css are also included
* Fix layer detection, should use `module.layer` directly since `module.resourceResolveData` is not alway presented. It lost when switching from `require()` to `import()` for page/layout component

This PR fixes (and simplifies) CSS loader rules, major things fixed with
this PR:
- (Tests added) Even if `appDir` isn't enabled, CSS/SASS/CSSM/SASSM
should still be transpiled for packages in node_modules, configured via
`transpilePackages`.
- They should be transpiled from other packages in the same monorepo
(not inside node_modules).

This PR adds a `--no-mangling` option to `next build` and fixes the `--profile` option so that you can use the React profiling build on production.
The advantage of disabling only mangling versus disabling minification altogether is that we still run terser and still benefit from DCE with this approach, so the `--no-mangling` does not impact performance as much.

Improvement to how the `app` and `pages` files conflict is shown.
Especially the last log line `"pages/" - "app/"` made it seem like you
should remove the `pages` folder altogether. This was a bug in how the
`''` case was displayed. After having a look at this I went further and
added exactly which file caused the conflict given that `app` allows you
to create `app/(home)/page.js` and such it saves some digging for what
the actual conflicting file is. Similarly in `pages` both
`pages/dashboard/index.js` and `pages/dashboard.js` are possible.
Before:
```
error - Conflicting app and page files were found, please remove the conflicting files to continue:
error - "pages/another" - "app/another"
error - "pages/hello" - "app/hello"
error - "pages/" - "app/"
```
After:
```
error - Conflicting app and page files were found, please remove the conflicting files to continue:
error - "pages/another.js" - "app/another/page.js"
error - "pages/index.js" - "app/page.js"
error - "pages/hello.js" - "app/hello/page.js"
```

This PR fixes the bug reported by @hanneslund (reproduction:
https://github.com/hanneslund/css-mod-import-test).
There can be multiple modules with the same resource, some of them can
be created via plugins (extracted by the mini-css plugin) and some can
be directly transformed via loaders (e.g. the CSS modules loader). In
these cases, we need to merge the resources generated by all of them.

This PR implements a configuration option in `next.config.js` to support
for rust-based MDX compiler (https://github.com/wooorm/mdxjs-rs).
Currently it is marked as experimental, as mdx-rs and loader both may
need some iteration to fix regressions.
When a new experimental flag is set (`mdxRs: true`), instead of using
`@mdx/js` loader `next/mdx` loads a new webpack loader instead.
Internally, it mostly mimics mdx/js's loader behavior, however actual
compilation will be delegated into next/swc's binding to call mdx-rs's
compiler instead.
I choose to use next-swc to expose its binding function, as mdx-rs
internally uses swc already and creating new binary can double up
bytesize (with all the complex processes of publishing new package).

logic between napi bindings / standalone binaries.

Allows you to specify multiple weights and styles for a
`@next/font/local` font family.
When generating a fallback font family it will pick the font file with
the weight closest to normal, this will typically make up most of the
text on a page.

Fixes#41856. There is no way to apply those loader rules to specific
directories, especially when `transpileModules` is used. This PR changes
that to be based on the issuer layer.

Removing the `hasReactRoot` condition and `__NEXT_REACT_ROOT` env var since next 13 requires latest react 18 to be installed, all the react 17 (non concurrent mode) compatible code can be dropped now.
Previously we use `path.join(compiler.context, chunk.name)` as the entry
name, which isn't always the case especially when there is the `src`
folder. This PR fixes that by using `appDir`.

Follows `reactStrictMode`. Still recommended to have it enabled (which is the default for new apps). This will become increasingly more important as other features on top of concurrent rendering are implemented.

This PR temporarily fixes#41884 by loosing the type check rules. I will
work on a follow up PR to type params better with tests.

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
Related: https://github.com/vercel/next.js/issues/41870
We currently only fallback to the global `runtime` option if the page
actually **needs** a runtime (not statically optimizable). That happens
for SSG (ISR) and SSR for pages/. But for app/, we will always need a
`runtime` to render server components.
Also in this PR, I improved the tests to actually **test** the runtime
to ensure it has `globalThis.EdgeRuntime` so it's not running in the
Node.js runtime
([ref](https://edge-runtime.vercel.app/features/available-apis#addressing-the-runtime)).
