This updates to the latest version of `node-file-trace` and leverages the new async fs handling with webpack. In a follow-up PR we will implement the async resolver to share resolving with webpack as well.
x-ref: https://github.com/vercel/nft/pull/236
This updates our `jest` configuration to no longer use `babel-jest` and instead uses `@swc/jest` which is much faster. This also updates to the latest version of `jest`, fixes our `tsconfig.json` used for tests (previously types in `node_modules` weren't resolved correctly), and ensures `next/dist` isn't un-necessarily transpiled in `jest`.

cjs package: Offers only CJS implementation (may not even have an `exports` field)
mixed package: Offers CJS and ESM implementation via `exports` field
pure esm package: Only offers an ESM implementation (may not even have an `exports` field)
pure cjs package: CommonJs package that prevents importing via `exports` field when `import` is used.
`*` This case will behave a bit unexpected for now, since `require` will return a Promise. So that need to be awaited. This will be fixed once the whole next.js bundle is ESM. It didn't work at all before this PR.
`**` This is a new Error when trying to require an esm package.
`***` For mixed packages we prefer the CommonJS variant to avoid a breaking change.

This Pull Request adds [Alex](https://alexjs.com/) to our documentation. It catches insensitive, inconsiderate writing.
The original PR (https://github.com/vercel/next.js/pull/25821) is too large so I have decided to break it down into smaller PRs. This PR is the first part. Then I will continue to add the rest of the documentation in smaller PRs.

@timneutkens it'd be great to get your input.
These changes introduce a new Babel loader that eliminates much of the existing overhead, resulting in better HMR speeds.
Multithreading is still in flight, and may be omitted if speed improvements end up being negligible. For now, the new loader is hidden behind an `experimental` flag.
Items to be completed before this PR is ready to merge:
- [x] reconfigure `ncc` to precompile the parts of `@babel/core` and `@babel/traverse` that we're accessing directly
- [x] change `@babel/core/...` imports to `ncc`ed version
- [x] ~~measure multithreading (not currently pushed) functionality, and include the functionality depending on the results~~ I'll open a separate PR for this
- [x] ensure TypeScript is happy with all imports as final step (`--no-verify` was used to bypass)
There will be two follow-up PRs:
- loader support for projects with custom `.babelrc`
- multithreaded loader (should the change we warranted after measurement)
* fixes a bundle size regression from webpack 4 to 5
* fixes these warnings during resolving build dependencies for packages using `exports`

* after a while cache entries that are unused and already persistent to disk are removed from the memory cache
* When are read again, they are restored from disk again
* Should play well together with adding and removing pages due to on-demand-entries
