Notify SyncNetworkChannel about GCM connection state

Notify SyncNetworkChannel about GCM connection state

This change propagates GCM connection state from GCMInvalidationBridge
to SyncNetworkChannel where based on this notification overall
invalidations state is updated.

This change still has issue that when GCM connection is down but HTTP request
succeeds then status is updated to NOTIFICATIONS_ENABLED. Fixing this
requires minor refactoring which I would like to pull into separate change.
