Andreas Kling c2fce0f19c LibWeb: Implement :host and :host(<compound-selector>) selector matching ...

The :host family of pseudo class selectors select the shadow host
element when matching against a rule from within the element's shadow
tree.

This is a bit convoluted due to the fact that the document-level
StyleComputer keeps track of *all* style rules, and not just the
document-level ones.

In the future, we should refactor style storage so that shadow roots
have their own style scope, and we can simplify a lot of this.
