Do not directly import app-render into base-server since base-server is
shared module for both nodejs SSR and edge SSR.

This adds a new `experimental.middlewarePrefetch` config with two modes
with the default being the `flexible` config.
- `strict` only prefetches when the `href` explicitly matches an SSG
route (won't prefetch for middleware rewrite usage unless manual
`href`/`as` values are used)
- `flexible` always prefetches ensuring middleware rewrite usage is
handled and also prevents executing SSR routes during prefetch to avoid
unexpected invocations

Removing the `hasReactRoot` condition and `__NEXT_REACT_ROOT` env var since next 13 requires latest react 18 to be installed, all the react 17 (non concurrent mode) compatible code can be dropped now.
Right now the SSG condition is determined _only_ based on
`supportsDynamicHTML`. However that `supportsDynamicHTML` flag can be
affected by bots too.
Here we exclude the `isBot` condition from the SSG flag, and set proper
status and meta tags for static HTML requests (and/or 404 cases).

The `target: serverless` config was deprecated a year ago starting in
[Next.js 12](https://nextjs.org/blog/next-12).
Tests were disabled in #41252 so we can now remove `target: serverless`
and all usage of `target` in `next.config.js`.

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.

When possible (`ReactRoot` enabled), we always use
`renderToReadableStream` to render the element to string and drop all
`renderToString` and `renderToStaticMarkup` usages. Since this is always
true for the Edge Runtime (which requires React 18+), so we can safely
eliminate the `./cjs/react-dom-server-legacy.browser.production.min.js`
module there
([ref](https://unpkg.com/browse/react-dom@18.2.0/server.browser.js)).
This reduces the gzipped bundle by 11kb (~9%). Let me know if there's
any concern or it's too hacky.

For some context:
[https://vercel.slack.com/archives/CGU8HUTUH/p1662124179102509](https://vercel.slack.com/archives/CGU8HUTUH/p1662124179102509)
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.

`config.experimental.serverComponents` is currently required to be
enabled or disabled together with `config.experimental.appDir` (which
means `serverComponents === appDir` otherwise it will throw) so there is
no reason to keep both of them. This PR removes `serverComponents` from
Next.js and only rely on `appDir` instead.

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)

Such bots typically navigate websites using hard navigations (as they
crawl one URL at a time). Respectively, they do not benefit from
prefetches at all, while increasing the cost of both the crawl and
operating the site.

This serves to add support for [Subresource
Integrity](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity)
hashes for scripts added from the new app directory. This also has
support for utilizing nonce values passed from request headers (expected
to be generated per request in middleware) in the bootstrapping scripts
via the `Content-Security-Policy` header as such:
```
Content-Security-Policy: script-src 'nonce-2726c7f26c'
```
Which results in the inline scripts having a new `nonce` attribute hash
added. These features combined support for setting an aggressive Content
Security Policy on scripts loaded.

This PR implements the logic to make next-app-loader able to match multiple routes.
The app loader is refactored to construct the tree recursively instead of within a loop, as there could be multiple branches. Similarly, when entering a new layout level or branch, we resolve both the slot name (defaults to `"children"`) and the segment.
In order to make that work, the loader has to know all matched app paths. This is passed in as the `appPaths` loader option, which is gathered when creating the entrypoint.

Check `pagesDir` to bypass empty pages folder when appDir is enabled
* Output empty loadable manifest for now if there's no `pagesDir`
* No custom aliases with all page extensions for `/_app`, `_document` if pagesDir is empty, only keep the built-in ones
* Check pagesDir in build/dev-server/eslint
* Type safe: change arguments of some APIs from optional to required, so that we won't mess up with default arguments
## Feature
As the title, support `has` match, `local` that works the same with the `rewrites` and `redirects` of next.config.js on middleware config. With this PR, you can write the config like the following:
```js
export const config = {
matcher: [
"/foo",
{ source: "/bar" },
{
source: "/baz",
has: [
{
type: 'header',
key: 'x-my-header',
value: 'my-value',
}
]
},
{
source: "/en/asdf",
locale: false,
},
]
}
```
