IVGCVSW-2398 Add no-op factory implementations for all backends for the

Equal operation

 * Add QueueDescriptor in WorkloadData.hpp
 * Add CreateEqual function in WorkloadFactory.hpp
 * Added stub implementation of the CreateEqual function in RefWorkloadFactory,
   NeonWorkloadFactory and ClWorkloadFactory
