Fixes https://github.com/vercel/next.js/discussions/32233⚠️ If you're looking at this PR please read the complete description including the part about incremental adoption.
## TLDR:
Official support for `<Link href="/about">About</Link>` / `<Link href="/about"><CustomComponent /></Link>` / `<Link href="/about"><strong>About</strong></Link>` where `<Link>` always renders `<a>` without edge cases where it doesn’t render `<a>`. You'll no longer have to put an empty `<a>` in `<Link>` with this enabled.
## Full context
### Changes to `<Link>`
- Added an `legacyBehavior` prop that defaults to `true` to preserve the defaults we have today, this will allow to run a codemod on existing codebases to move them to the version where `legacyBehavior` becomes `false` by default
- When using the new behavior `<Link>` always renders an `<a>` instead of having `React.cloneElement` and passing props onto a child element
- When using the new behavior props that can be passed to `<a>` can be passed to `<Link>`. Previously you could do something like `<Link href="/somewhere"><a target="_blank">Download</a></Link>` but with `<Link>` rendering `<a>` it now allows these props to be set on link. E.g. `<Link href="/somewhere" target="_blank"></Link>` / `<Link href="/somewhere" className="link"></Link>`
### Incremental Adoption / Codemod
The main reason we haven't made these changes before is that it breaks pretty much all Next.js apps, which is why I've been hesitant to make this change in the past. I've spent a bunch of time figuring out what the right approach is to rolling this out and ended up with an approach that requires existing apps to run a codemod that automatically opts their `<Link>` usage into the old behavior in order to keep the app functioning.
This codemod will auto-fix the usage where possible. For example:
- When you have `<Link href="/about"><a>About</a></Link>` it'll auto-fix to `<Link href="/about">About</Link>`
- When you have `<Link href="/about"><a onClick={() => console.log('clicked')}>About</a></Link>` it'll auto-fix to `<Link href="/about" onClick={() => console.log('clicked')}>About</Link>`
- For cases where auto-fixing can't be applied the `legacyBehavior` prop is added. When you have `<Link href="/about"><Component /></Link>` it'll transform to `<Link href="/about" legacyBehavior><Component /></Link>` so that your app keeps functioning using the old behavior for that particular link. It's then up to the dev to move that case out of the `legacyBehavior` prop.
**This default will be changed in Next.js 13, it does not affect existing apps in Next.js 12 unless opted in via `experimental.newLinkBehavior` and running the codemod.**
Some code samples of what changed:
```jsx
const CustomComponent = () => <strong>Hello</strong>
// Legacy behavior: `<a>` has to be nested otherwise it's excluded
// Renders: <a href="/about">About</a>. `<a>` has to be nested.
<Link href="/about">
<a>About</a>
</Link>
// Renders: <strong onClick={nextLinkClickHandler}>Hello</strong>. No `<a>` is included.
<Link href="/about">
<strong>Hello</strong>
</Link>
// Renders: <strong onClick={nextLinkClickHandler}>Hello</strong>. No `<a>` is included.
<Link href="/about">
<CustomComponent />
</Link>
// --------------------------------------------------
// New behavior: `<Link>` always renders `<a>`
// Renders: <a href="/about">About</a>. `<a>` no longer has to be nested.
<Link href="/about">
About
</Link>
// Renders: <a href="/about"><strong>Hello</strong></a>. `<a>` is included.
<Link href="/about">
<strong>Hello</strong>
</Link>
// Renders: <a href="/about"><strong>Hello</strong></a>. `<a>` is included.
<Link href="/about">
<CustomComponent />
</Link>
```

Changes to the beforeInteractive strategy to make it work for streaming
Splitting `beforeInteractive` into two strategies `beforeInteractive` at the _document level and `beforePageRender` for page level <Scripts>
This PR makes sure `renderPage` calls `renderShell` in concurrent features, and `renderToString` if not.

This ensures we strip ansi encoding from serialized errors as it causes the error to be illegible when rendered. This also adds a test for global CSS import being missing and then fixed.

There wasn't a strong reason to choose `renderToStream` over `renderToStaticMarkup` for the document wrapper. But due to problems like #35870, we can switch back to the static renderer for now.
Fixes#35870.

- `test/integration/critical-css`

This fixes `router.isReady` being incorrect in dev mode due to the `isAutoExport` field being false from `hasConcurrentFeatures` being flagged similar to the static 404 in https://github.com/vercel/next.js/pull/35749. While investigating this I also noticed we aren't properly detecting react 18 when no `next.config.js` is present.

* Read the proper page file from either pages directory or from node_modules (inernal pages like _app, _document)
* Only reading page runtime when `reactRoot` is enabled, reduce time for react 17 apps
When using streaming SSR decodeText is called repeatedly with incoming
chunks of data. In that case a multi-byte character may occasionally
split between chunks, causing corruption. By setting the TextDecoder
option 'stream' to true, and reusing the same TextDecoder instance,
TextDecoder will memorise “unfinished” characters and decode them when
the next chunk comes.
