NIFI-14655: Fixed Stateless Engine so that it is able to surface CPU Time, GC Time, etc. in Processor Stats
Do not shutdown thread pool for stateless group until we've given processors a chance to gracefully stop; also ensure that even if components support batch processing that we immediately stop if the flow's desired state transitions to stopped

> When Processors are run using the Stateless Execution Engine, we see the Stats History for CPU Usage, etc. but the stats all show zero. This is the case even when NiFi is configured to calculate these stats (nifi.properties has non-zero value for the {{nifi.performance.tracking.percentage}} property)
