We previously used an empty optional to denote that a ReferrerPolicy is in the default empty string state. However, later additions added an explicit EmptyString state. This patch moves all users to the explicit state, and stops using `Optional<ReferrerPolicy>` everywhere except for when an option not being passed from JavaScript has meaning.
