This continues off of https://github.com/vercel/next.js/pull/36285 fixing some of the failing test cases noticed when running the E2E tests against deployments. After these are resolved the tests will be added to our CI flow after each canary release.

This PR fixes a bunch of bugs and it now supports:
- Importing a client component from a nested server component (a.server → b.server → c.client).
- The `export from` syntax in server component (`export { default } from './a.server'`)
- Native modules in server components (currently broken)

Fixes#35449
Include the shared components (from source code) is in client bundles, previously we lost them so that the client components imported by them are lost in module graph
* let flight server loader apply to all pages and imported modules (except node_modules at the moment)
* if it's a shared component from source code, include it in client bundle
* ignore handling node_modules at the moment (due to the limitation support of esm imports with RSC)

Part of #31506 and https://github.com/vercel/next.js/discussions/34179. This PR ensures that in the `nodejs` runtime, the flight data is statically stored as a JSON file if possible. Most of the touched code is related to conditions of static/SSG/SSR when runtime and/or RSC is involved.

We are currently using `!!ComponentMod.__next_rsc__` as the hint for the renderer to tell if the component is a server component, however that export field (`__next_rsc__`) is assigned to client components (`.client.[ext]`) as well.
This PR adds a new `__next_rsc_server__` field which is only true when the component is a server component so the renderer can handle client components correctly.

Simplify the esmodule detection. If there's any import/exprt usage, it will return `Module` in ast.type otherwise `Script` when `isModule` is set to `"unknown"`
We need to handle cjs cases for client/server components when they're compiled to commonjs in some cases.
e.g. if there's an internal `_app.server.js` in nextjs, the assets in the dist files are compiled to cjs by swc. Or any 3rd party libraries are consumed could be cjs only.
### How it works
* Detect the source file is ESM or CJS first by detect if there's any ESM import/export
* Append the new exports or collect exports info based on the module type
.substr() is deprecated so we replace it with .slice() which works similarily but isn't deprecated

## Summary
This PR adds a new `worker` strategy to the `<Script />` component that automatically relocates and executes the script in a web worker.
```jsx
<Script
strategy="worker"
...
/>
```
[Partytown](https://partytown.builder.io/) is used under the hood to provide this functionality.
## Behavior
- This will land as an experimental feature and will only work behind an opt-in flag in `next.config.js`:
```js
experimental: {
nextScriptWorkers: true
}
```
- This setup use a similar approach to how ESLint and Typescript is used in Next.js by showing an error to the user to install the dependency locally themselves if they've enabled the experimental `nextScriptWorkers` flag.

- For Partytown to work, a number of static files must be served directly from the site (see [docs](https://partytown.builder.io/copy-library-files)). In this PR, these files are automatically copied to a `~partytown` directory in `.next/static` during `next build` and `next dev` if the `nextScriptWorkers` flag is set to true.

Since we are applying this loader to more files, and these two simple RegExp filters will be executed ~70 times per entry, it's an easy optimization to move the RegExp creation outside and merge related testers into the RegExp.

Fixes: #31993
* Remove the simple component checking in middleware ssr
* Leverage existing components checking for Component / App / Document, if any of these component is not valid react type or is undefined nextjs will error in dev mode with redbox. Like above.

Fixes the problem that global `process` variable has only the `env` field.
Also fixed the issue that the `env` field is empty when the `process` module is used as the value of the variable (which happens when the module is contained in a dependency of application).

This PR removes the experimental `optimizeImages` flag. This feature was designed to automatically add preload tags for images, but I was never able to get it to do a very good job of selecting the images that actually need preloading.
This feature never graduated from experimental and in fact we never even publicized it as an experimental feature for people to try.
Additionally, even if someone was using this feature, it wouldn't have a functional effect, only a performance effect (removal of some preloads).
For those reasons, I believe it is safe to remove this functionality and that it is not a breaking change.
### Changes
* node server and webpack should share the same logic: auto detect react 18 and enable `reactRoot`
* fallback `_error` should use functional document if concurrent rendering is enabled
### Test
* Remove the hard code `reactRoot: true` in test suite
* Test some react-18 test suite with nodejs runtime
Related to #34185, this PR reduces the size of chunk that contains web-server.ts from 1.14mb to 210.8kb, by splitting base-http and api-utils into different environments.
Only affected thing is we can't have SSG preview mode for the web runtime via `getStaticProps`.

This PR ensures that the test "should render 500 error correctly" doesn't break when `runtime` is set to `nodejs` with `serverComponents` enabled.
This test case is now moved to the "basic" suite to ensure it doesn't break in both runtimes. And "should not bundle external imports into client builds for RSC" is enabled for the `nodejs` runtime too.

As per React 18 recommendation, we should use e.g. `renderToReadableStream` whenever we use `createRoot`. This is particularly important for currently supported suspense features like `React.lazy` to work properly during SSR.
However, unless you have opted in to streaming support (via [the `runtime` flag](https://github.com/vercel/next.js/pull/34068)), we will wait until `onCompleteAll` before sending it (via the `generateStaticHTML` flag).

Fixes#33879
The `export default xxx` statement is slightly different from estree when exporting an arrow function instead of identifier in swc.
We also need to capture arrow exports.
This fixes our parsing of params with i18n for optional catch-all routes and ensures a regression test catches this case.

Fixes: https://github.com/vercel/next.js/issues/30631
Cleans up the code of the middleware SSR loader and the web server. Currently the page components and render options are provided to the server via `globalThis` which is not ideal.
Instead we can inject `extendRenderOpts` and `loadComponent` to the web server. Since this is the the minimal mode and we'll need to handle `?flight` requests, we update the server render opts upon `updateRenderOpts` (In the future this should be changed to be passed to `requestHandler` to avoid race conditions).
Currently, we can't fully get rid of the `__server_context` global as we call `getBuildId` in the base server constructor.

In the web runtime, currently we use `absolute500Path || absoluteErrorPath` to act like `/_error`. This PR fixes the behavior to use the `/pages/500.js` for 500 errors and `/pages/_error.js` for 500 fallback and other errors.

(#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 removes `loadEnvConfig` and `chalk` from the base server while keeping the same behavior for the node server.
