MiniMax-M2.5 B200: add EP, FP8 KV cache, disable radix cache

Based on validated benchmark configs in SemiAnalysisAI/InferenceX#1010,
tp:4/ep:4 and tp:2/ep:2 are now confirmed for B200. Also enables 2-GPU
selection for B200, adds --kv-cache-dtype fp8_e4m3 and --disable-radix-cache
as B200-specific flags per the benchmark script.
