Reviewed by Ryosuke Niwa.

Add a field in `CSSPseudoSelectors.json` that represents whether a pseudo takes a required or optional argument, and use it to:
- generate `isOnlyPseudoClassFunction` as `CSSSelector::pseudoClassRequiresArgument`
- generate `isOnlyPseudoElementFunction` as `CSSSelector::pseudoElementRequiresArgument`
- add ASSERTs when serialization code hasn't been provided for pseudos with an optional or required argument
