Bug 1543394 - Don't update visited state of all <html:link> elements …

…in chrome docs. r=smaug

I don't think there's a point in making <link> elements match :visited, and it's
an issue for Chrome docs because some chrome code can run before we have a
profile.

Make the already-existent workaround for localization links work more generally.

There's no interop across browsers here anyhow:

  w3c/csswg-drafts#3817

tracks that.
