Testcase Scenarios :

 1) Test hipHostMalloc() api with ptr as nullptr and check for return value.
 2) Test hipHostMalloc() api with size as max(size_t) and check for OOM error.
 3) Test hipHostMalloc() api with flags as max(unsigned int) and validate
 return value.
 4) Pass size as zero for hipHostMalloc() api and check ptr is reset with
 with return value success.
