Renamed ElectricalComponentState to ElectricalComponentStateSnapshot

The state message in this case is a snapshot of the state of the
electrical component's composite sttae at a given time. The name
`ElectricalComponentStateSnapshot` is more descriptive and
accurately reflects the purpose of the message.
