style: Add an AllLinksVisitedAndUnvisited for invalidation.

Browse source 
Otherwise, tests like the following fail, given we always match as unvisited,
and we'd never mark the link as needing invalidation.

<!doctype html>
<style>
a {
  color: red !important;
}

.foo :visited {
  color: green !important;
}
</style>
<div>
  <a href="https://google.es">visit me</a>
  <button onclick="this.parentNode.className = 'foo'">Then click me</button>
</div>
