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)
