IVGCVSW-2377 Add no-op factory implementations for all backends for the

Greater operation

 * Added QueueDescriptor in WorkloadData.hpp
 * Added CreateGreater function in WorkloadFactory.hpp
 * Added stub implementation of the CreateGreater function in RefWorkloadFactory,
   NeonWorkloadFactory and ClWorkloadFactory
 * Added GreaterLayer stub implementation
 * Renamed ArithmeticBaseLayer to ElementwiseBaseLayer
