Renamed a method named Service since there is a class Service

There is a class Service in services/content/service.h which
makes it unsuitable to have other symbols named Service in
content. There was a local helper function named Service in
content/browser/notifications that caused a clash in jumbo builds
and this patch renames that method NotificationService()
