* All future work submitted to @p stream will wait until @p event reports completion before
* beginning execution.

* Flags include:
* hipEventWaitDefault: Default event creation flag.
* hipEventWaitExternal: Wait is captured in the graph as an external event node when
* performing stream capture
*
* This function only waits for commands in the current stream to complete. Notably, this function
* does not implicitly wait for commands in the default stream to complete, even if the specified
* stream is created with hipStreamNonBlocking = 0.
