Add support for "in" that works like the group variant, but use any parent (so it does not require an explicit group element).

I'm doing a follow up on #13751 where I propose a new modifier, that is a simplified "group-*" without an explicit parent.
There are many times when the styling is based on the parent state, but it is not important which parent, there are many examples of that on the tests with the form of:
[.checked &]:underline, but there are many other cases, for example:in-aria-busy: If any parent is busy is enough, we don't care which parent it is.in-data-active: This is part of an active element.The syntax is quite simple, the implementation is clean and the generated css is shorter than using
group-*or[.checked_&]:underline, and it also allows using variants like data- and aria-.Hope you like the idea.
