@brief Creates a memcpy node to copy from a symbol on the device and adds it to a graph.

@param [out] pGraphNode - Pointer to graph node that is created. @param [in] graph - Instance of graph to add the created node to. @param [in] pDependencies - const pointer to the dependencies of the memcpy execution node. @param [in] numDependencies - Number of the dependencies. @param [in] dst - Pointer to memory address of the destination. @param [in] symbol - Device symbol address. @param [in] count - Size of the memory to copy. @param [in] offset - Offset from start of symbol in bytes. @param [in] kind - Type of memory copy. @returns #hipSuccess, #hipErrorInvalidValue
