It would be useful to have a way to select img elements that are using an attachment as their data source.

Some things that need review here:
- the name of the pseudoclass
- the way it’s made to not parse at runtime if the attachment element isn’t enabled
- the lack of an explicit mechanism to force style resolution when an img gains an attachment, because currently the DOM tree mutation just makes it work

If this is apple-internal only, should it have a -apple- prefix?
