Clarify required error information in lmcontrol API

### What

Currently, the lmcontrol API will only provide an enum value as error information indicating if a RunTarget change happed due to a RecoveryAction or a StateManager request.

It is not possible to identify which components have failed in case the transition is triggered by a RecoveryAction.
It is not possible identify intermediate transitions that lead to the final RunTarget.
Knowing in which active RunTarget the error occurred requires tracking of the active RunTarget by the user of the API.

We shall clarify the use cases that need to be supported and extend the interface with the required information.
