Compare `Vector<Parser::ComponentValue>` directly instead of serializing them into strings first. This is required for the upcoming changes where we would compare previous and new sets of custom properties to figure out whether we need to invalidate descendant elements. Without this change `equals()` would show up being hot in profiles.
