Async memory copy callback tracing + memory copy size (#791)

* Async memory copy tracing update

- rocprofiler_buffer_tracing_memory_copy_record_t: thread_id and bytes
- support ROCPROFILER_CALLBACK_TRACING_MEMORY_COPY
- init_public_api_struct can fully construct

* Testing for callback async copy tracing
