Yongye ZhuandClaude Opus 4.7 d0e6514bf8 [Attention] Add TOKENSPEED_MLA backend for DeepSeek R1 prefill + decode on Blackwell ...

Wires the tokenspeed_mla CuTe DSL kernels into vLLM as a new MLA backend,
covering both prefill (tokenspeed_mla_prefill) and decode
(tokenspeed_mla_decode). Targets Blackwell (SM100) with FP8 KV cache and
DeepSeek R1 MLA dimensions; users opt in via -ac
'{"backend":"TOKENSPEED_MLA","mla_prefill_backend":"TOKENSPEED_MLA"}'.
Includes numeric parity tests against the trtllm reference kernels.
