API - hipStreamIsCapturing
Negative Testcase Scenarios : Negative
  1) Check capture status with null pCaptureStatus.
  2) Check capture status with hipStreamPerThread and null pCaptureStatus.
Functional Testcase Scenarios :
  1) Check capture status with null stream.
  2) Check capture status with hipStreamPerThread.
  3) Functional : Create a stream, call api and check
     capture status is hipStreamCaptureStatusNone.
  4) Functional : Start capturing a stream and check
     capture status returned as hipStreamCaptureStatusActive.
  5) Functional : Stop capturing a stream and check
     status is returned as hipStreamCaptureStatusNone.
  6) Functional : Use hipStreamPerThread, call api and check
     capture status is hipStreamCaptureStatusNone.
  7) Functional : Start capturing using hipStreamPerThread and check
     capture status returned as hipStreamCaptureStatusActive.
  8) Functional : Stop capturing using hipStreamPerThread and check
     status is returned as hipStreamCaptureStatusNone.
