  [CSS] Support :visited as the scoping root selectors
https://bugs.webkit.org/show_bug.cgi?id=296947
rdar://157588890

Reviewed by Antti Koivisto.

We statically take the scoping root selectors into account
to determine if we are potentially resolving visited/link style.

We track wheter we have match visited during scoping root matching, and
pass this result to normal style rule matching.

Add slightly more complex case when the scoping root is a link, but the 
matching is done with class selector.
