1. remove useless loggings. 2. Fix conditional compilation for HIP. 3. Fix problems of test_pass_generation_pipeline.py. It calls paddle.distributed.init_parallel_env() at first, then auto.Engine calls _init_comm(), which will calls process_group.instantiate(). However, init_parallel_env() will call paddle.distributed.barrier(), it will call CreateNCCLEnvCache and create corresponding NCCLCommContext. But dev_id is not set, as a result, NCCLCommContext's dev_ctx is not initialized.
