LibJS: Don't force property table reification on Shape::property_count()
Previously whenever you would ask a Shape how many properties it had, it would reify the property table into a HashMap and use HashMap::size() to answer the question. This can be a huge waste of time if we don't need the property table for anything else, so this patch implements property count tracking in a separate integer member of Shape. :^)
