Add failing test for the back button download bug. Created it as a new
app given that adding it to the existing `app` suite did not reproduce
the issue for some reason.
The underlying reason is that we need to add `Vary: __rsc__,
__next_router_prefetch__` to ensure Chrome does not cache the response
and serve it on back button.
The download was caused by the `application/octet-stream` content type,
but that was just a consequence of serving the wrong response.

Consider the following middleware which redirects to
`/path/to#fragment`.
```ts
import { NextResponse } from 'next/server';
export async function middleware(request) {
const url = new URL('/path/to#fragment', request.url);
return NextResponse.redirect(url);
}
```
However, it actually redirects to `/path/to`, namely it discards the
fragment part in the destination URL `#fragment`. This is because
`NextURL.toString()` does not append that part. This PR fixes the bug.

It’s possible that global CSS imports, that come from node_modules, are
marked as side effect free because of possible `sideEffects: false` in
the external package's package.json. In that case, we still need to
handle global CSS imports as side effects on the server because we need
to collect them and avoid tree-shaking for these modules.
You can take a look at the test case to see what exactly happened.

There is no need to use the href as key in our case because it's pure
during SSR and it won't re-order on the client. By using `index` we can
avoid some duplicate bytes here:

- Enable newNextLinkBehavior. See #36436
- Run next/link codemod on test suite
Note that from when this lands on apps trying canary will need to run
the new-link codemod in order to upgrade.
Ideally we have to detect `<a>` while rendering the new link and warn
for it.

The solution is to call `stream.push(null)` to trigger the `end` event
which allows `getRawBody` to run completely.

The PR continues from #41392.
In #41392 the `dev ? cache-busting : empty` is executed per stylesheet instead of per page rendering. Since rendering link tags would be a hot path at the server, it might have accidentally introduced a performance overhead. The PR fixes that.
Note, this change also makes `Date.now()` only execute once instead of per stylesheets, however, this will most likely not cause any issues.
Similar to #40872 `useSearchParams` now returns a `URLSearchParams` instance instead of a plain object.

Follows #41150, bump the server-side code pre-compile target to Node.js
14.0.0.
This could also potentially reduce the size of the server bundle and
increase the performance (less transformation and fewer inlined swc
helpers).

Since we have already bundled dependencies for server layer, so the
shared deps chunk group is not needed anymore.
Also changing to esm assets import with next internals for edge function
and middleware build.
The changes are originally from #41337, try to land them separately.
This ensures we don't re-use edge workers locally as they are meant to
be isolated.

This PR introduces breaking changes by renaming components.
- Rename `next/image` to `next/legacy/image`
- Rename `next/future/image` to `next/image`
The diff is very confusing because both components are very similar so git got confused.
In this PR, I'm inlining the require for some of the modules that I
noticed take a bit of time to evaluate on a cold boot and are not needed
most of the time.
With this, it's an extra ~15ms win on cold boots (tested locally) and we
are now at around 68ms (started from 110+).

MDX no longer supports GitHub flavored markdown (GFM) by default since v2, instead requiring a plugin: https://mdxjs.com/guides/gfm/
Since GFM is extremely popular (for example, you need it if you want to use markdown tables), this change paves the cow path, making it clear that next.config.mjs is now supported and allows you to import remark-gfm.
The `ReadOnlyHeaders` class extends the `Headers` class that is provided
via a polyfill. This incurs some costs the first time it's created
because we need to load that polyfill. This saves approximately 10ms on
my machine on a cold request.
This is only useful when a user does not access headers during the
request of course and when the runtime does not support fetch naitvely.
