The upcoming generated types will match those for pseudo-classes: A PseudoElementSelector type, that then holds a PseudoElement enum defining what it is. That enum will be at the top level in the Web::CSS namespace. In order to keep the diffs clearer, this commit renames and moves the types, and then a following one will replace the handwritten enum with a generated one.
