LibWeb/CSS: Keep invalid parts of <forgiving-selector-list>s around

Browse source 
Selectors like `:is(.valid, &!?!?!invalid)` need to keep the invalid
part around, even though it will never match, for a couple of reasons:

- Serialization needs to include them
- For nesting, we care if a `&` appeared anywhere in the selector, even
  in an invalid part.

So this patch introduces an `Invalid` simple selector type, which simply
holds its original ComponentValues. We search through these looking for
`&`, and we dump them out directly when asked to serialize.
