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 removes the config for the `commons` chunk.
I think the idea was that modules are that in all pages are put into a `commons` chunk, but that breaks when next/dynamic comes into play, which also creates chunks. So the `totalPages` condition is broken and could lead to too many modules placed into the commons chunk.
Example: 2 pages, each has one next/dynamic. Both on demand chunks include module A. page 1 includes module B and next/dynamic on page 2 includes module B. A and B are placed into commons. commonjs chunk is loaded in page 1 and both next/dynamic. Page 1 would load module A even while it doesn't need it.

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
Mark some previously experimental swc compiler options as stable under a new `compiler` option

Instead of branching rendering based on Node.js and browser/web runtimes, we should just use the web version for now, which can run as-is on versions >=16.5.0 of Node.js, polyfilling `ReadableStream` on older versions when necessary.
There are a few potential downsides to this, as React is less able to optimize flushing and execution. We can revisit that in the future though if desired.

A few people including myself have been looking to use Relay with Next.JS and want to use the new Rust Compiler. This is my stab at an implementation.
### How it works?
Finds all `graphql` tagged template experssions and replaces them with `require`s to the file generated by Relay.
### Where I need help
- I've only worked with Rust a handful of times so I would appreciate any feedback on my use of language features.
- Is there any performance overhead to many duplicate usages of `require`? I imagine there's a cache in place but I want to be sure.
- I've added some unit tests & integration tests but I might be missing some use cases. Feel free to comment some use cases I'm not thinking about.
- [x] Related issues linked using `fixes #number`
- [x] Integration tests added
- [ ] Documentation added
- I haven't added any docs since this is an experimental API.
## Documentation / Examples
You're expected to be running the Relay Compiler along side Next.JS when you're developing. This is pretty standard. I wouldn't expect people to have any problem with this.
### Usage
In your `next.config.js`
```js
module.exports = {
experimental: {
relay: {
language: 'typescript', // or 'javascript`
artifactDirectory: 'path/to/you/artifact/directory' // you can leave this undefined if you did not specify one in the `relay.json`
}
}
}
```

After discussing with @sokra, seems that the proposed solution is split in two:
* We need to make sure that the `process` polyfill uses `global.process` if available. This is because middlewares are bundled using `browser` target and therefore `process.env.MY_ENV` gets shimmed into `require('process').env.MY_ENV`.
* Allow `process.env` to be statically analyzed for dependencies so they will be exported to the manifest.
Related issues:
* should fix#33043.

The issue is that with Middleware we are introducing client compilation on a new layer. When a middleware changes (or is dropped after some time), Webpack reorganizes non-user modules as they are duplicated across different layer. This is currently triggering a full reload.
This also brings tests for HMR:
- Refresh on a Middleware change
- HMR works after a middleware compilation change.

When using the web runtime with SSR streaming, this PR significantly improves the build speed for large applications when there're large modules shared by most pages.
With another optimization, `react-dom` will now be excluded in the web runtime build if it's imported in the application. It will only take effect in the client bundle.

By conditionally importing `react-dom/server` under the web runtime and reusing `renderToReadableStream` instead of `renderToStaticMarkup`, we can get rid of the legacy browser React DOM server from the runtime. ~Furthermore we can make the build target `es6` for the SSR middleware, and make some code paths tree-shakable (done in another PR).~
Together this makes the runtime ~32kb smaller.

When you edit your code, and Next.js is compiling the application, a compilation indicator appears in the bottom right corner of the page.
In some cases this indicator can be misplaced on the page, for example, when conflicting with a chat launcher. To change its position, open `next.config.js` and set the `buildActivityPosition` in the `devIndicators` object to `bottom-right` (default), `bottom-left`, `top-right` or `top-left`.
I also added the documentation for both `devIndicators.buildActivity` & the new `devIndicators.buildActivityPosition`.

This updates the `outputFileTracing` to fix a few cases we noticed where files weren't caught and also ensures we match webpack's `esm` resolving so that we don't include `cjs` files when webpack expects `esm`, it also updates to the latest `@vercel/nft` version which removes the caching in favor of ensuring the `reasons` map contains all parents allowing us to trace all entries in one `nodeFileTrace` run and the collect the separate files for each entry from the `reasons` map giving us much better performance/reliability.
This also ensures we don't include static image imports when enabled in the traces since they can drastically increase deployment size on larger projects.
This prevents useless warnings about querystring.
```
warning next > native-url > querystring@0.2.1: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
warning next > node-libs-browser > url > querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
```
This ensures we don't add the no-op resolve alias when rewrites aren't used for the server resolving since it is still needed while tracing server files.
