Add LongBench v2 support for DeepSeek (#2410)

* Add LongBench v2 support for DeepSeek

- Add long-bench-eval dependency to requirements.txt
- Refactor run_evaluation.sh to support both standard and LongBench v2 tasks
- Add dynamic max_length configuration (40960 for longbench tasks)
- Implement vLLM server-based evaluation for LongBench
- Add helper functions for server lifecycle management
- Support up to 40K context length evaluation with 512 threads
