`node-sass` v5 introduced support for Node.js v15, which is not supported by v4. However, Next.js currently errors with
```
Error: Node Sass version 5.0.0 is incompatible with ^4.0.0.
```
when attempting to build with `node-sass` 5.0.0. This error comes from `sass-loader`. They have recently released version 10.0.5 which supports `node-sass` 5.0.0 (PR <https://github.com/webpack-contrib/sass-loader/pull/899>, release <https://github.com/webpack-contrib/sass-loader/releases/tag/v10.0.5>).
This makes sure we don't use es6 syntax when compiling the `web-vitals` package with `ncc` since that breaks IE11 compatibility

This upgrades to ncc@0.25.0 and fixes the previous bugs including:
* ncc not referenced correctly in build
* Babel type errors
* node-fetch, etag, chalk and raw-body dependencies not building with ncc - these have been "un-ncc'd" for now. As they are relatively small dependencies, this doesn't seem too much of an issue and we can follow up in the tracking ncc issue at https://github.com/vercel/ncc/issues/612.
* `yarn dev` issues
Took a lot of bisecting, but the overall diff isn't too bad here in the end.
This adds inlining for Babel and the Babel plugins used in next.
This is based to the PR at https://github.com/vercel/next.js/pull/18823.
The approach is to make one large bundle and then separate out the individual packages from that in order to avoid duplications.
In the first attempt the Babel bundle size was 10MB... using "resolutions" in the Yarn workspace to reduce the duplicated packages this was brought down to a 2.8MB bundle for Babel and all the used plugins which is exactly the expected file size here.
This will thus add a 2.8MB download size to the next package, but save downloading any babel dependencies separately, removing a large number of package dependencies from the overall install.
This updates to the latest ncc@0.24.1 release.
Initially I thought chalk needed to be removed to make this work, but it turns out it was a caching issue.
I've also added a cache clear to the rebuild command to avoid these issues hopefully in future.
This is a prerequisite to being able to ncc inline the Babel dependencies in next.js.
The removal of preset-modules is based on replacing it with preset-env under `targets: { esmodules: true }`, as per the guidance from the package (https://www.npmjs.com/package/@babel/preset-modules):
> Starting from @babel/preset-env 7.9.0, you can enable the bugfixes: true option to get the same behavior as using @babel/preset-modules, but with support for custom targets. If you need to target browsers with native modules support (like this preset does), you can use targets: { esmodules: true }.
From the above, I'm pretty sure this is entirely a backwards compatible change, apart from the change to the runtime plugin list being visible. Perhaps @developit can confirm this as well.
This makes sure the image optimizer doesn't de-animate images by transforming them with sharp since sharp doesn't currently handle outputting animated images

This adds the initial changes outlined in the [i18n routing RFC](https://github.com/vercel/next.js/discussions/17078). This currently treats the locale prefix on routes similar to how the basePath is treated in that the config doesn't require any changes to your pages directory and is automatically stripped/added based on the detected locale that should be used.
Currently redirecting occurs on the `/` route if a locale is detected regardless of if an optional catch-all route would match the `/` route or not we may want to investigate whether we want to disable this redirection automatically if an `/index.js` file isn't present at root of the pages directory.
TODO:
- [x] ensure locale detection/populating works in serverless mode correctly
- [x] add tests for locale handling in different modes, fallback/getStaticProps/getServerSideProps
To be continued in fall-up PRs
- [ ] add tests for revalidate, auto-export, basePath + i18n
- [ ] add mapping of domains with locales
- [ ] investigate detecting locale against non-index routes and populating the locale in a cookie

Babel-preset-env includes includes optional chaining and
nullish-coalescing since [7.8.0](https://github.com/babel/babel/releases/tag/v7.8.0).
In this diff I removed these plugins from next preset to prevent
dependency duplication when their newer versions are out.
This PR replaces `prop-types-exact` (only used in this location) with manual property checking.
Right now, malformed properties sent to `<Link>` are silently handled and only emit a warning in the console.
This leads to confusing/unexpected errors because we try to read a value that is undefined.
To fix this, we'll now throw a proper error when `<Link>` is misused. **This still isn't optimal, however, because we don't have a component stack trace we can give the user**.
We're not going to be able to give the user actionable instructions until React 16.14 at a minimum.

This adds the following Node.js core polyfills only when the import is used:
- `path`
- `stream`
- `vm`
- `crypto`
- `buffer`
Fixes#15948
We'll have a separate issue about adding warnings for the usage of these modules in the browser, some polyfills like crypto are quite heavy and generally not needed for most applications (included accidentally through node_modules).
