Remove dead spec hash helpers

Now that update propagation is tracked via ActionableRevision and
observedGeneration, the integrity-hash helpers have no callers:

- AutoscalingRunnerSet.Hash and AutoscalingListenerSpec.Hash lost their
  last callers in this change.
- ListenerSpecHash, RunnerSetSpecHash, EphemeralRunnerSet.EphemeralRunnerSpecHash
  and EphemeralRunnerSpec.Hash were already unreferenced.
