[Cherry-Pick] [BugFix] resolve get_save_output_v1 socket name conflicts between multiple instances (#6758)

[liyonghua0910]

Motivation

When FD_USE_GET_SAVE_OUTPUT_V1 is enabled, the ZMQ socket name is currently derived only from local_data_parallel_id. In multi-instance deployments on the same machine, different instances can end up using the same socket name, which may cause IPC

Modifications

• Updated the get_save_output_v1 socket naming rule to include local_engine_worker_queue_port in addition to local_data_parallel_id
• Aligned both server and client socket names across:
  • token_processor
  • gpu_model_runner
  • metax_model_runner
  • xpu_model_runner
• Updated tests/output/test_get_save_output_v1.py to reflect the new socket naming logic
