@brief Creates a memcpy node and adds it to a graph.

@param [out] phGraphNode - Pointer to graph node that is created. @param [in] hGraph - Instance of graph to add the created node to. @param [in] dependencies - const pointer to the dependencies of the memcpy execution node. @param [in] numDependencies - The number of dependencies. @param [in] copyParams - const pointer to the parameters for the memory copy. @param [in] ctx - context related to current device. @returns #hipSuccess, #hipErrorInvalidValue
