This testfile verifies the following scenarios of hipHostMalloc API
1. Basic scenario of hipHostMalloc API
2. Negative Scenarios of hipHostMalloc API
3. Allocating memory using hipHostMalloc with Coherent flag
4. Allocating memory using hipHostMalloc with NonCoherent flag
5. Allocating memory using hipHostMalloc with default flag
