LibWeb: Wrap PseudoElements stored in SimpleSelector in a class
No functional impact intended. This is just a more complicated way of writing what we have now. The goal of this commit is so that we are able to store the 'name' of a pseudo element for use in serializing 'unknown -webkit- pseudo-elements', see: https://www.w3.org/TR/selectors-4/#compat This is quite awkward, as in pretty much all cases just the selector type enum is enough, but we will need to cache the name for serializing these unknown selectors. I can't figure out any reason why we would need this name anywhere else in the engine, so pretty much everywhere is still just passing around this raw enum. But this change will allow us to easily store the name inside of this new struct for when it is needed for serialization, once those webkit unknown elements are supported by our engine.
