Kmd notify improvements [1/n]: Quick KMD sleep optimization

Browse Source 
- KmdNotifyProperties struct for CapabilityTable that can be extended by
  incoming KmdNotify related optimizations
- Quick KMD sleep optimization that is called from async events handler
- Optimization makes a taskCount check in busy loop with much smaller
  delay than basic version of KMD Notify optimization
