\brief Launches an executable graph in a stream

Executes \p graphExec in \p stream. Only one instance of \p graphExec may be executing at a time. Each launch is ordered behind both any previous work in \p stream and any previous launches of \p graphExec. To execute a graph concurrently, it must be instantiated multiple times into multiple executable graphs.

If any allocations created by \p graphExec remain unfreed (from a previous launch) and \p graphExec was not instantiated with ::cudaGraphInstantiateFlagAutoFreeOnLaunch, the launch will fail with ::cudaErrorInvalidValue.
