Doing so is more trouble than its worth.  The CSS tokenizer doesn't
care what string-quoting character was used, or how many whitespace
characters are in a run, so that information isn't preserved into the
parsing stage.  Let's not add layering violations just to "fix"
something that still wouldn't work anyway (since it *still* doesn't
actually do anything, despite being mutable/constructable).

I still have an action from months ago to investigate actual usage of
CSSCharsetRule, to see if we can just drop it entirely from the CSSOM.
 I'll bet we can.
