  CL: Update event creation routines
  
  Move backend construction after frontend construction
  completes. This avoids potential undefined behavior
  if backend construction tries to access members of
  half-constructed frontend object.
  
  Add virtual onEventCreate routine for any actions that
  need to be performed after cmd event has been created.
  
  Additionally, this also fixes incorrect timestamp values
  when queue profiling is enabled for the VK backend.
  This was due to a missed event association to the
  cmd queue.
