For some context:

Continuation of #40221 and #40227
Adds `experimental.fontLoaders`.
SWC next-font-loaders (#40221) transforms font loader (e.g. #40227) call
expressions into an import with the function call arguments as a query.
The imports will be matched by `next-font-loader`. It runs the
configured font loaders - emits font files and returns CSS. Exports are
added, and the font-family is made locally scoped. The returned CSS is
turned into a CSS module with `css-loader` which lets you consume the
font-family.
`FontLoaderManifestPlugin` creates a manifest of the preloaded font
files for each entrypoint. Preload/preconnect are then added in
`_document.tsx` if any font files were found for that path.

## Feature
- [x] Implements https://github.com/vercel/next.js/discussions/40112
- [x] Integration tests added
Adds a new option to the current font optimization to enable
experimental font size adjust
The new `optimizeFonts` config will be
```
optimizeFonts: {
inlineFonts: true,
experimentalAdjustFallbacks: false,
},
```
To enable the feature, set `experimentalAdjustFallbacks: true`
`optimizeFonts: false` will disable the entire feature (including
inlining google font definition)

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.
The shared utils file included an import from `react` (because it was using `createContext`) which seems to be unnecessary in the Middleware bundle.
With this PR and steps #34425 laid out, the bundle size did decrease without breaking functionality.
Fixes#34425
