* compatiable new comm library upgrade for c_allgather, c_reduce, c_reduce_scatter and c_scatter.

* Remove useless comments in process_group.py

* Polish code style.

* Fix some problems.

* Remove use fluid api in phi comm_context_manager.

* Add PPADDLE_WITH_CUDA and PADDLE_WITH_NCCL micro judgement.

* Fix bug of HIP architecture.

* Fix some problems.
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.

* Fix some problems.

* Polish code.

* Revert compatiable upgrade for communication operators. Their upgrades
will be submitted in another PR.

* Remove fluid header files in phi files.

* Remove useless comments.

* Fix problems of hip arch.
