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.

This PR depends on #35242 and #35243. It allows the global runtime to be unset, as well as enables static optimization for Fizz and RSC pages in the Node.js runtime. Currently for the Edge runtime pages are still always SSR'd.
Closes#31317.

## 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.

This PR fixes#31517.
Partially implements #31317 and #31506. There're also some trade-offs made with this PR: since we can't know if a certain runtime will be used or not beforehand, we have to start both runtime compilers (Node.js and Edge) and then generate entrypoints correspondingly.
Note that with this PR, the global runtime is still required to use the per-page runtime.

* Add failing colon rewrite test
* add test fixture
* better colon rewrite tests
* middleware rewrite colon tests with query parameters
* fix#31523
this addresses the symptom but the real systemic issue is that prepareDestination is called on rewrite/redirect URLs, which have no defined special behavior for colons and they should not be compiled at all
* hack around prepareDestination to skip compiling x-middleware-rewrite
this is a bit nicer than just escaping colons, but ideally we find a way to obviate prepareDestination
* obviate prepareDestination for x-middleware-rewrite handling
* don't clobber rewrite query data
* omit redundant type
* catch up to main
* It looks like newUrl should contain only pathname

This PR introduces a way to use WASM in middlewares.
Next.js will find all `.wasm` imports in middlewares and load them as `WebAssembly.Module` objects, which then can be later instantiated.
The metadata will be stored in `middleware-manifest.json`

This PR adds the `X-Powered-By` and `Content-Type` headers to responses sent by the web server. The latter enables compression for the Edge runtime. Still, the web server doesn't have `Content-Length` and `ETag` as the response is usually dynamic.

This PR brings back @Schniz awesome contribution to bring in bodies to middleware. It was reverted to leave it out of the stable release and to have some time to test it out in canary before officially releasing it. This PR is simply a `cherry-pick` of his original work.
Closes: #30953

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.
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 allows to have a more streamlined API for rewrites.
Since middlewares are code and not static configurations, we can allow people to
delete query params and not just overwrite them.
**⚠️ Warning ⚠️** this is a breaking change in query parameter behavior with middlewares, but the API will make more sense now. Compare the following:
```diff
import {NextResponse} from 'next/server'
export default function middleware({ nextUrl }) {
- nextUrl.searchParams.set('ignored-query-param', '');
+ nextUrl.searchParams.delete('ignored-query-param'); // 🎉
return NextResponse.rewrite(nextUrl);
}
```
Since this is breaking change, we're adding a warning every time we find a query param that is missing, and eventually--the warning will be deleted.
I don't think we need to worry about older versions of Next.js as the current behavior is misleading: merging query parameters make sense for static rewrites, but not for middlewares where you have access to all the query parameters and can manipulate them freely.

(#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.
Subtask of #31506
* move `serverBuildDir` and getter function of `publicDir` to next-server as only used place
* simplify `getMiddlewareInfo`, remove `distDir` and other params could be accessed from web server itself
Related to #31506, this PR adds `getPrerenderManifest` and `getRoutesManifest` methods to provide manifest files to the base server. In the future, we can consider making these methods async, or provide necessary manifests from the very top.

This reverts the type for the `conf` field in `ServerOptions` isn't changed to require all `NextConfig` values as this is a breaking change from what was previously required. We should investigate making sure this field is normalized when it is provided via a user.

This PR fixes#30398
By default Next will polyfill some fetch APIs (Request, Response, Header and fetch) only if fetch is not found in the global scope in certain entry points. If we have a custom server which is adding a global fetch (and only fetch) at the very top then the rest of APIs will not be polyfilled.
This PR adds a test on the custom server where we can add a custom polyfill for fetch with an env variable. This reproduces the issue since next-server.js will be required without having a polyfill for Response which makes it fail on requiring NextResponse. Then we remove the code that checks for subrequests to happen within the **sandbox** so that we don't need to polyfill `next-server` anymore.
The we also introduce an improvement on how we handle relative requests. Since #31858 introduced a `port` and `hostname` options for the server, we can always pass absolute URLs to the Middleware so we can always use the original `nextUrl` to pass it to fetch. This brings a lot of simplification for `NextURL` since we don't have to consider relative URLs no more.

Since #31939 is going to move the `Document` components, we can't rely on `DefinePlugin` to provide environment variables. This PR passes them as render opts instead. We can't just force this to be bundled like e.g. `next/dynamic`, because we use it internally.
