Trace final actor state

[Stebalien]

At the moment, we trace the state of every invoked actor, but we don't include the state after it returns. For completeness, we should include the after state giving us:

1. The remaining balance.
2. The final state.
3. Whether or not it selfdestructed.

@aarshkshah1992 can we sync on this issue this week. I can talk with Eva if this is really needed by Blockscout, etc.
