/* Intension : Multidevice test to verify hipMemcpy2D(Async) behavior. Test verifies hipMemcpy2D behavior
               when one of the device memory is not owned by current device.
               i)  H2D & D2H -> Device memory is not owned by current device
               ii) D2D -> source memory is not owned by current device
   Note : To make it simple at present checking API functionality not validating values.
