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

@param [out] pGraphNode - Pointer to graph node that is created. @param [in] graph - Instance of the graph to add the created node. @param [in] pDependencies - const pointer to the dependencies of the memset execution node. @param [in] numDependencies - Number of dependencies. @param [in] childGraph - Graph to clone into this node @returns #hipSuccess, #hipErrorInvalidValue
