 *  Tests for hipDrvPointerGetAttributes API
 Functional Tests:
   1. Pass multiple device related attributes in the attributes of hipDrvPointerGetAttributes API
      for the device pointer and check the behaviour
   2. Pass device and host attributes in the attributes of hipDrvPointerGetAttributes API and validate the behaviour
   3. Pass invalid pointer to hipDrvPointerGetAttributes API and validate the behaviour.

 Negative Tests:
  1. Pass invalid numAttributes
  2. Pass nullptr to attributes
  3. Pass nullptr to data
  4. Pass nullptr to device pointer
