Invalidate :-webkit-any-link for visited state changes.

We did style invalidation for :visited and :link, but UA style uses
color: -webkit-link with :-webkit-any-link and let -webkit-link be
translated into two different colors in the implementation instead of
using :visited and :link in the stylesheet.

Adding style invalidation of :-webkit-link as well. We already did that
for attribute changes on <a> and <svg:a>.
