This PR adds support for complex `addUtilities()` configuration objects
that use child combinators and other features.
For example, in v3 it was possible to add a utility that changes the
behavior of all children of the utility class node by doing something
like this:
```ts
addUtilities({
'.red-children > *': {
color: 'red',
},
});
```
This is a pattern that was used by first-party plugins like
`@tailwindcss/aspect-ratio` but that we never made working in v4, since
it requires parsing the selector and properly extracting all utility
candidates.
While working on the codemod that can transform `@layer utilities`
scoped declarations like the above, we found out a pretty neat
heuristics on how to migrate these cases. We're basically finding all
class selectors and replace them with `&`. Then we create a nested CSS
structure like this:
```css
.red-children {
& > * {
color: red;
}
}
```
Due to first party support for nesting, this works as expected in v4.
## Test Plan
We added unit tests to ensure the rewriting works in some edge cases.
Furthermore we added an integration test running the
`@tailwindcss/aspect-ratio` plugin. We've also installed the tarballs in
the Remix example from the
[playgrounds](https://github.com/philipp-spiess/tailwindcss-playgrounds)
and ensure we can use the `@tailwindcss/aspect-ratio` plugin just like
we could in v3:
