[Orc] Handle hangup messages in SimpleRemoteEPC

On the controller-side, handle `Hangup` messages from the executor. The executor passed `Error::success()` or a failure message as payload.

Hangups cause an immediate disconnect of the transport layer. The disconnect function may be called later again and so implementations should be prepared. `FDSimpleRemoteEPCTransport::disconnect()` already has a flag to check that:
