Title::getPageLanguage has complex logic to determine the effictive language of the page. PageRecord is a storage layer primitive and should not haveknowledge of such logic, nor should PageStore. The effective content language of a page needs to be determined programmatically, see discussion on the ticket. Bug: T278591 Change-Id: Ic26f6f7690499b3dd87982e3822881fd473cfd68
