Minimaxm2.5 nvfp4 b200 (#996)

* Add MiniMax-M2.5 NVFP4 vLLM benchmark config for B200

* Use vLLM nightly image and update benchmark script for MiniMax-M2.5 NVFP4 B200

* Update MiniMax FP4 B200: use v0.19.0-cu130 image, sync perf-changelog

* Optimize search space and update perf-changelog for minimaxm2.5-fp4-b200-vllm

Expand search space from tp2/tp4 to tp1/tp2/tp4/tp8 with expert parallel
and dp-attn variants. Sync perf-changelog from origin/main and append entry.

* Update minimaxm2.5 fp4 b200 benchmark script with dp-attn support

Add DP_ATTENTION env var and refactor parallelism into PARALLEL_ARGS
to support data-parallel attention mode. Also update server flags:
gpu-memory-utilization 0.90, add max-cudagraph-capture-size and
max-num-batched-tokens, remove block-size and FLASHINFER env export.

* Add tp2/tp4 non-EP search-space entries for minimaxm2.5-fp4-b200-vllm

Widen concurrency sweep with standalone tp2 and tp4 entries (conc 4-512)
alongside existing EP variants for both 1k1k and 8k1k seq-len configs.

* Update perf-changelog.yaml with new line
