Stop rebuilding the counter style cache from every style update. That made unrelated restyles pay the full counter-style cost even when no relevant stylesheet state had changed. Dirty the cache when stylesheet rule caches are invalidated and rebuild it on the first counter-style lookup instead. Also make cold cache rebuilds include user stylesheets. Add regression tests covering insertRule() and replaceSync() updates that should make newly defined counter styles take effect.
