[BackgroundSync] Use appopriate type parameters for WebCallbacks (4/4)

This series of CLs fixes WebCallback parameter types used in BackgroundSync.

 - WebSyncRegistration* (ownership transferred)
  => PassOwnPtr<WebServiceWorkerResponse>
 - bool* (ownership transferred)
  => bool
 - WebVector<WebSyncRegstration*>* (ownership transferred)
  => const WebVector<WebSyncRegistration*>&
 - WebPermissionStatus* (ownership transferred)
  => WebPermissionStatus
 - WebSyncError* (ownership transferred)
  => const WebSyncError&
