Support top level static `robots.txt` and `sitemap.xml` as metadata
route in app directory. When those files are placed in top root
directory
Refactored a bit the page files matching logic, to reuse it between dev
server and build
Closes NEXT-267
Add support for cases like:
```js
const foo = async function () {}
export default foo
const bar = async function() {}
export { bar }
```
Also fix a bug where nested async function declarations are mistakenly
counted as actions.
Fixes NEXT-800.
`test/development/acceptance-app/hydration-error.test.ts` has a lot of tests because I ported all the tests in https://github.com/facebook/react/blob/main/packages/react-dom/src/__tests__/ReactDOMHydrationDiff-test.js. Running all those tests takes a lot of time, and to include all the different cases is overkill.
This PR removes most tests but keeps one test case per type of hydration error, and also one using suspense. This makes more sense, it should only test that all the different hydration error messages are picked up.
Similar to #46888, this PR adds support for the case:
```js
async function foo () {}
export default foo
```
...where you export an ident as a default export expression.

The docs are wrong for now, this limitation is just in `pages/`, you can
use it anywhere in `app/`.
Since `app/` is still not stable we will emit that warning in all files
outside of `app/`.
This ensures we leverage the fetch cache when calling
`generateStaticParams` and also ensures paths with
`generateStaticParams` without `dynamicParams = false` don't error when
only partial params are provided.

Add unique identifier `@app@` / `@pages@` / `@root@` for entry key of on
demand entries, so that they'll be unique for each path when the page
key is similar bewteen app and pages like (`"app/page"` and
`"pages/page"` will both end up with `/page`)

Currently the codemod always runs `root.toSource()`, recreating the
source from the AST. But this can sometimes add unexpected semicolons to
files that actually didn't get updated by the codemod. This PR adds a
check to see if the AST has been updated before running
`root.toSource()`, otherwise it just returns the original source.
This PR adds the support for unnamed default export expression support
`export default async function () {}` in a "use server" entry, with
corresponding test.
Also fixed an existing bug that the default exported action's name
should be aligned with the export name, which is `"default"`.
Closes NEXT-769.
Add a timeout to the Google Fonts fetch calls in dev. In case they
aren't fetched in time, the fallback font is used instead.
Currently if font fetching fails due to network errors in dev, the
loader is not cached. Every change on a page that uses a font makes it
retry to refetch the font. But, if the network is slow enough to cause
timeouts, that means that every change would force the user to wait for
the timeout before the page being updated. Because of this, the PR also
enables the loader to be cached on error. The drawback is that you would
have to delete the `.next` folder to retry to get the actual font in
case it got cached after failing.
Closes NEXT-726

## What?
This PR has its main goal to improve the experience of opening/reviewing
a PR.
It improves the PR template, as well as extends PR auto-labeling.
## Why?
There are 2 parts to the PR template:
- Individual contributors: The current template accommodates for the
most common cases individual contributors use to contribute. (I.e.
fixing bugs, updating/adding examples, addressing documentation issues).
The new template keeps this at the top.
- Next.js team: As maintainers, we should try to explain PRs as if
someone with less context would review them. This should also help with
backreferencing PRs in issues and follow-up PRs and make it easier to
follow changes, understand trade-offs better at the time, and help new
team members catch up over time, etc.
## How?
The template is written in a comment instead of Markdown, so when the PR
is opened, most of the template is hidden to make it less verbose.
The checkboxes we've had before are not shown, but we already auto-label
PRs based on the path of the files that have been touched, so the
checkboxes showed redundant information.

This updates to no longer skip caching POST or authed requests with the
fetch cache and instead we bail when `cookies()` or `headers()` is used
prior which is a better heuristic to signal user specific data would be
related to the fetch request.

Currently all helper functions are exported from huge utils files. This
moves the helper functions to their own files, this approach aligns
better with the rest of the codebase.
The unit tests are split up and colocated with the function it tests.
Also added some missing tests.
Plus some overall cleanup, added comments and fixed types.

This PR makes `typedRoutes` stricter by constraining generics in `Route` to type string. I've also made generating types for routes a bit more efficient by moving `redirects` and `rewrites`'s processing to the plugin's constructor since `rewrites` and `redirects` don't change in both dev and prod.
I've also been trying to fix a bug where route types doesn't generate all the routes (some appear, some don't), but I've got no clues since that doesn't seem easy to reproduce (perhaps it only happens in my case?)

Because there is a TS error when is set just a string:
`TS2322: Type '() => string' is not assignable to type '(loadingProps: DynamicOptionsLoadingProps) => Element | null'. Type 'string' is not assignable to type 'Element'.`
Turbopack uses a different format for its css module classnames [0].
This adds and uses a helper function to the next-font tests to assert
against these classnames when testing with Turbopack. Ideally these
tests could be more behavioral (e.g. asserting on rendered dimensions),
but these can't capture things like fallback fonts.

Since the default export syntax is not `fnDecl` but `fnExpr` I added two new methods to abstract out all the transform logic and made both `visit_mut_fn_decl` and `visit_mut_fn_expr` use that.
Next step is to support default exports without an ident (`export default async function () {}`).
Fixes NEXT-768.

Since we have 2 server compilers (node and edge), the `serverActions`
object will always get overridden by the second compilation during `next
build`. Like the client reference manifest, we need to have 2 objects
for each compiler and merge them when outputting the asset.
Besides that, to avoid `export default` being tree-shaken as unused
export, I changed the loader to use CJS `module.exports` instead. Can't
easily figure out a proper way for now but we plan to create separate
worker for the action endpoint and this will be gone then.
Fixes NEXT-759, read NEXT-761 for the full future plan.
