/*
Added Negative and Functional tests for hipPointerGetAttribute API

Functional Scenarios:

1. Allocate memory using different Allocation APIs and check whether
   correct memory type and device oridinal are returned.

2. Allocate device variable and get the pointer info by calling hipPointerGetAttribute API
   with HIP_POINTER_ATTRIBUTE_DEVICE_POINTER/HIP_POINTER_ATTRIBUTE_START_ADDRESS
   and Launch kernel with device variable and verify whether the pointer variable of
   hipPointerGetAttribute is getting updated or not

3. Allocate device memory in GPU-0 and get the pointer info in peer GPU

4. Allocate device memory and get the buffer ID by calling
   hipPointerGetAttribute API with HIP_POINTER_ATTRIBUTE_BUFFER_ID,
   DeAllocate and Allocate the memory again and ensure that the buffer ID is unique

5. Allocate host memory and get the device ordinal by calling
   hipPointerGetAttribute API with HIP_POINTER_ATTRIBUTE_DEVICE_ORDINAL
   and ensure that it matches with CUDA result(which returns 100)

6. Allocate managed memory with different flags and trigger
   hipPointerGetAttribute with the following flags HIP_POINTER_ATTRIBUTE_MAPPED and verify the behaviour
