If importing an external module inside a Server Component (`.server.js`), it shouldn't be bundled into the client. Only client components should be kept.

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.
`isAutoExport` should be `false` when `concurrentFeatures` is enabled.

To run middleware we are using a **sandbox** that emulates the web runtime and keeps a module cache. This cache is shared for all of the modules that we run using the sandbox while there are some module-level APIs that must be scoped depending on the module we are running.
One example of this is `fetch` where we want to always inject a special header that indicate the module that is performing the fetch and use it to avoid getting into infinite loops for middleware. For those cases the cached implementation will be the first one that instantiates the module and therefore we can actually get into infinite loops. This is the reason why #31800 is failing.
With this PR we refactor the sandbox so that the module cache is scoped per module name. This means that one execution of a middleware will preserve its cache only for that module so that each execution will still have its own `fetch` implementation, fixing this issue. Also, with this refactor the code is more clear and we also provide an option to avoid using the cache.

Fixes#30897
This PR fixes the linked issue where rewrites are not being applied for locale. It adds the corresponding test but also, as it was added in debugging process, it introduces a helper to read/write into the `request` object.
We are currently writing directly into the request by casting to `any` and then using flags like `_nextRewrote`. Instead, this PR puts all of this metadata under a symbol so it is not directly accessible. This also allows to have a single place where all of this metadata is listed so we can add comments describing the purpose of each flag.
In the same way, there is metadata written in the querystring. This is adding some types for it in order to throw some visibility on where is this metadata accessed. In an upcoming PR we can move all of it to the `request` object if possible to simplify the system.

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.

This fix the custom 404 is not rendering properly and can’t be built in web runtime when `concurrentFeatures` is enabled. We force 404 page to be rendered outside of middleware ssr. Then it could be the real fallback 404 page in next-server when any routes is not macthed.

This PR improves error handling in the SSR middleware. Previously the response was sent out synchronously, and and errors were silently swallowed. There was no `.catch` for `renderToHTML`. This changes the middleware to be asynchronous, which waits until the initial Document to be rendered correctly and then starts the streaming.
With this change we can also send correct status code when there're immediate errors before Fizz.

With this PR we are updating the way we check the usage of `eval` and other dynamic code evaluation (like `new Function`) for middleware. Now instead of simply showing a warning it will behave differently depending on if we are building or in development.
- Development: we replace the dynamic code with a wrapper so that we print a warning only when the code is used. We don't fail in this scenario as it is possible that once the application is built the code that uses `eval` is left out.
- Build: we detect with tree shaking if the code that will be bundled into the middleware includes any dynamic code and in such scenario we make the build fail as don't want to allow it for the production environment.

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 fixes cases where not all `package.json`s were being added to the traces correctly while using webpack's resolving with the `outputFileTracing`. The specific case notice while testing has been added as an integration test to ensure it is working as expected.
Follow-up to https://github.com/vercel/next.js/pull/29473 after additional testing it seems we need to ensure the `main` field is used when tracing packages during builds so that `module` isn't being used unexpectedly.
Follow-up to https://github.com/vercel/next.js/pull/29307 this ensures the `blurDataURL` is correctly prefixed with the `basePath` in development since we use the `_next/image` endpoint to generate the placeholder in dev mode.

We're no longer currently planning on supporting caching for dynamic responses, so we can do some cleaning & simplification:
* Multiplexing can be removed since we only ever subscribe once (via `RenderResult.pipe`, described below)
* `RenderResult.toUnchunkedString` can become synchronous since static responses are never chunked
* `RenderResult.forEach` can become `RenderResult.pipe` which helps encapsulate some of the details of `RenderResult`
* Expose minify in next-swc
* Expose minify in js binding
* Use new minify function in terser plugin
* Only upload changed binary artifact
* Build next-swc binaries
* Add swc license info to copied file

Adds `RenderResult`, replacing the `string` that `renderToHTML` used to return, with an `Observable`-like API that callers can use to subscribe and get a callback when chunks are available to flush, etc.
This is the last architectural change needed for streaming. There are, however, other things currently standing in the way of streaming. For example, it is common to mutate `res` in `getServerSideProps` to do routing work, or write headers, before fetching page data. This pattern effectively nullifies any advantages of streaming. I may do a follow-up PR that adds an experimental alternative for applications not using React 18, but the main purpose for this support is for Suspense and Server Components.
For that reason, there's no actual streaming here yet: instead we just flush a single chunk. A follow-up PR will add support for streaming suspense boundaries in React 18.
