buffet: Add state change ID to state queue
Each state update will now increment a state change ID to help correlate
device state and command updates.
Right now, each call to NotifyPropertiesUpdated() will increment the ID.
This functionality will be used in subsequent CLs to implement ordering
of state and command updates on GCD server.
