Small QOL improvements to `RenderResult` and `RouteModule` setup. This
also adds a test to verify that headers aren't sent on responses that
have already been sent.

### What?
this forces all tests to use turbopack independent of the way they invoke next dev
### Why?
some tests were not running turbopack
fixes WEB-1187
### What?
* allow to use `runtime = "edge"` for app dir in turbopack
* move common imports from next-app-loader to
`packages/next/src/server/app-render/entry-base.ts`
* move common turbopack code to communicate between JS and Rust into
separate files
### Why?
A lot test cases depend on edge rendering
### How?

This contains the original POC for `next build --turbo`. The implementation is _just enough_ to get pages building, and doesn't support the app router yet.
I'll write more details here on the implementation and what the next steps are next week.
Necessary changes on the Turbo side: https://github.com/vercel/turbo/pull/4998
Make sure we are using `var` instead of `const` as we always put the new
appended statements to the end of the module body, but they can still be
referenced before in the HOC case in the runtime. This causes a runtime
error.
Tl;dr: `a = 1; var a` is fine, but `a; const a = ...` will result in a
compilation error.
Closes#49344.
Remove the Server CSS manifest and related logic, and use the chunkGroup
CSS files instead for each entry to inject stylesheet links.
Why was that manifest needed in the first place? When implementing CSS
collection for RSC and nested layout initially, we collect CSS imports
at each layer and create corresponding client entries. But then soon got
hit by the problem of duplication and improper tree-shaking. Two layers
can have the same CSS imported so we solved it in a way that "if an
upper layer imports this module, skip it in child layers". Note that
this is deduped by module, so we need to keep the information of "layer
(entry) → CSS modules" somewhere, in a manifest.
Another reason is that we create the client entry before Webpack
optimizes modules, so we can inject the client entry into the same
compilation. But that means the collected client modules from the server
layer are not properly optimized (DCE). **This is a general issue at the
moment that's not specifically related to CSS, although using that
manifest to collect DCE'd info and join the original collected CSS files
with that info temporarily solved it.** That's why I disabled some tests
related to font CSS collection and want to improve it in a more general
way.
Why is that not needed anymore? Main reason is to keep a good balance
between duplication and number of chunks, and delegate the decision to
Webpack's splitChunks plugin. It is not possible to get to a point of 0
duplication unless we ship every CSS module as a single chunk. And since
in #50406 we made the duplication better but at the chunk asset level,
instead of the original module level.
Prior work: #50406, #50610.
This removes the `__internal_nextjs_integration_test` compile-time feature. This would end up requiring an additional set of build targets for running integration tests was only used for two cases:
* Determining whether to read from an env var to load mocked Google fonts responses in next/font/google tests. This now uses the presence of this variable to determine whether to use mocked responses.
* Enabling the `next-dev/serializable` feature. This is now set directly instead.
Test Plan:
* Integration tests with Turbopack.
* Manual test of next/font/google with Turbopack
### What?
* enable turbopack tests in new CI
* split pre-build step into native and JS builds to allow to start
native tests faster
* update swc_core to sync with turbo
* update turbopack
### Why?
Running our test suite is still important as long we don't have the full
integration test suite enabled.
### Turbopack updates

Instead of using azAvgWidth for next/font/google, use xWidthAvg as the webpack implementation does. For now, next/font/local in both the webpack and Turbopack implementations continue to use azAvgWidth. We should align these in the future.
Test Plan: We now pass 26 next/font tests in Turbopack, up from 22.
For RSC server layer so far we bundle all dependencies, ESM format is the better one rather than CJS to analyze and tree-shake out the unused parts. This PR changes pick the condition names that are in ESM format first for server layer.
Also fixes the misorder of condition names of edge runtime, `conditionNames` should only contain either ESM or CJS, previously the main fields are mixed with conditon names which is not expected for webpack, we separate them now.
Since we're picking ESM instead CJS now, the error of require `exports * from` doesn't exist anymore, but if you're using a CJS dependency which require a ESM package, it will error. This is the existing behavior for our webpack configuration but could happen on server layer bundling
Other related changes:
* Imports are hoisted in ESM, so migrate`enhanceGlobals` to a imported module
* Use `...` to pick the proper imports by import expression, and prefer the `react-server` / `edge-light` condition names for corresponding cases
* Remove edge SSR duplicated `middleware` export checking
Move as much of codeowners as possible to use Vercel Spaces.
1. Makes `@timneutkens @ijjk @shuding @huozhi @feedthejim` global owners
2. Make the `@vercel/next-js` team _optional_ owners of **/docs**,
**/errors**, and **/contributing**, makes team owners of a few packages
as per old config.
3. Make `@vercel/devex` (docs and devrel) owners of **/docs**,
**/errors**, and **/contributing**
4. Make `@vercel/devrel` (devrel only) owners of **/examples**
5. Make `@vercel/web-tooling` owners of specific files and folders (as
per old config)
Leaves @styfle as owner of **image** files on the old config since this
pattern `/**/*image*/** ` can't be used with Vercel Spaces.
Note: We cannot add * or / at the end of files.
