Andreas Kling 8beb7c7700 LibWeb: Cache whether there are any :has() selectors present ...

As useful as they may be to web developers, :has() selectors complicate

Let's have StyleComputer keep track of whether they are present at all
in the current set of active style sheets. This will allow us to
implement fast-path optimizations when there are no :has() selectors.
