Zijie Tian e874229adc 📝 docs: add comprehensive GPU-only vs Offload benchmark results ...

- Add --block-size argument to bench.py for configurable KV cache block size
- Update bench_offload_results.md with complete benchmark analysis:
  - GPU-only: XAttention shows +15% to +41% speedup
  - CPU Offload: XAttention shows -14% to -59% slowdown
  - Block size 4096 recommended for best performance
  - Document why XAttention hurts Offload mode (transfer bottleneck)
