* [Do not merge] Make changes to api_args
* Support HIP 7.0 API changes
- Provide ROCPROFILER_SDK_ variants of ROCPROFILER_ version defines
- Provide ROCPROFILER_SDK_COMPUTE_VERSION
- hipCtxGetApiVersion changes parameter from int* to unsigned int*
- hipMemcpyHtoD and hipMemcpyHtoDAsync changed void* to const void*
* Fix comment
