Code Review
This pull request adds support for ModelOpt MXFP8 models by introducing a new quantization configuration and associated linear method. The changes are well-structured and add valuable new functionality. My review includes a few points of feedback regarding documentation accuracy, consistency in MoE support, and an opportunity to refactor for code clarity and reuse.

The "torch" backend is temporary (can be used for debug in the future).
Backend FLASHINFER_CUTLASS will be added in the future:
flashinfer-ai/flashinfer#2464
Can be added after the flashinfer PR is merged, and flashinfer version is bumped in vLLM.

Purpose
Add support for ModelOpt MXFP8 dense models.
No support for MoE yet.
Related PRs
NVIDIA/Model-Optimizer#736
Test Plan
Use this LLM model (BF16):
https://huggingface.co/nvidia/OpenMath2-Llama3.1-8B
Convert the model to MXFP8 using ModelOpt:
The command above will generate a checkpoint
nvidia/OpenMath2-Llama3.1-8B-MXFP8.Compare performance (tokens/sec) and accuracy (gsm8k) of the BF16 and MXFP8 models.
Test Result
Performance (tokens/sec):
Measured on B200:
vllm bench throughput --model $MODEL_PATH \ --tensor-parallel-size 1 \ --trust-remote-code \ --async-scheduling \ --backend vllm \ --dataset-name random \ --random-prefix-len 0 \ --random-input-len 1024 \ --random-output-len 1024 \ --max-num-seqs 128 \ --num-prompts 512BF16
MXFP8
Accuracy (GSM8K):
lm_eval \ --model vllm \ --model_args pretrained=$MODEL_PATH,max_model_len=4096,enforce_eager=True,attention_backend=TRITON_ATTN \ --tasks gsm8k \ --batch_size auto --limit 300BF16
