[JENKINS-40161] Allow StepExecution.onResume to throw Exception

Proposal:

Change onResume to throw Exception. (Would still be binary-compatible.) FlowExecutionList.ItemListenerImpl.onLoaded would then need to catch exceptions and call StepContext.onFailure. Like AbstractStepExecutionImpl, this would rely on transient fields holding the contextual object; the improvement would be that a failure in StepContext.get would stop anything else in onResume (such as the setupTimer methods in TimeoutStepExecution, SleepStep.Execution, or DurableTaskStep.Execution) from running.
