/**
Negative Testcase Scenarios :
1) Pass stream as nullptr and verify there is no crash, api returns error code.
2) Pass graph as nullptr and verify there is no crash, api returns error code.
3) Pass graph as nullptr and  and stream as hipStreamPerThread verify there
   is no crash, api returns error code.
4) End capture on stream where capture has not yet started and verify
   error code is returned.
5) Destroy stream and try to end capture.
6) Destroy Graph and try to end capture.
7) Begin capture on a thread with mode other than hipStreamCaptureModeRelaxed
   and try to end capture from different thread. Expect to return
   hipErrorStreamCaptureWrongThread.
