  CL: Create frontend event and pass to enqueue APIs
  
  Since frontend cl_event object does not depend on enqueue
  API routines, we can construct it early and then pass to
  mImpl enqueue API calls (for any backend that needs it).
  
  Also update backend routines to init their backend
  event implementations using frontend event object.
