Since r835809, list-items respect to counter-* properties, but we didn't
invalidate list-items on updating the properties.

LayoutCounter::LayoutObjectStyleChanged(), which is called whenever
counter-* properties are changed, invalidates ListItemOrdinal too.

* LayoutCounter::LayoutObjectStyleChanged() calls new function
  ListItemOrdinal::ItemCounterStyleUpdated()

* ListItemOrdinal::ItemInsertedOrRemoved() is renamed to ItemUpdated(),
  and it adds support of inclusive invalidation.

* ListItemOrdinal::ItemInsertedOrRemoved() and
  ItemCounterStyleUpdated() call ItemUpdated().

* counter-set-002.html
 - Fix the flakiness
 - Add list-items before/after the updated node
