  Vulkan: Split Serial class into UniqueSerial and Serial
  
  This CL splits Serial class into two classes: UniqueSerial and Serial.
  UniqueSerial supports the object unique serial usage where there is ==
  and != operator but no > or < comparison. UniqueSerial can have invalid
  value, but Serial will not have invalid value (in next CL). The main
  reason is for next CL we can further optimize out the invalid value
  check in the QueueSerial comparison.
