@brief Creates a memory allocation node and adds it to a graph

@param [out] pGraphNode - Pointer to the graph node to create and add to the graph @param [in] graph - Instance of the graph node to be added @param [in] pDependencies - Const pointer to the node dependencies @param [in] numDependencies - The number of dependencies @param [in, out] pNodeParams - Node parameters for memory allocation, returns a pointer to the allocated memory. @returns #hipSuccess, #hipErrorInvalidValue
