Make BackgroundSyncRegistration a proper class

This CL refactors content::BackgroundSyncManager::BackgroundSyncRegistration into content::BackgroundSyncRegistration. It also moves it from a struct into a class for better access control. In a followup CL the BackgroundSyncRegistration will become refcounted (so that the clients can own the registrations after the BackgroundSyncManager no longer cares about them). For more information see the bug.
