+1) Add 1D memcpy node to graph and verify memcpy operation is success for all memcpy kinds(H2D, D2H and D2D).

+2) Allocate memory on default device(Dev 0), Perform memcpy operation for 1D arrays on Peer device(Dev 1) and

 Negative -
 1) Pass pGraphNode as nullptr and check if api returns error.
 2) When graph is un-initialized argument(skipping graph creation), api should return error code.
