MLECO-3659: Improvement for NPU PMU counters
The NPU idle count could have been erraneously high as
the counters were always running. This change utilises
callback functions to start/stop the counters only when
the inferences start/stop executing on the NPU.
Changes have been made to cache maintenance functions
called from within the NPU driver's pipeline to reduce
the overhead caused by these.
