A precision trick for quantization of DeepGEMM. If
export PER_TOKEN_QUANT_FP8_USE_FINEGRAINED_RANGE=1, this trick will be applied to all activation quantization of DeepGemm. In detail, a coefficient (constant value which is 7.0) will be multiplied by the maximum value per-token. This is to ensure that the quantized values are more concentrated in the high-precision region of the fp8 data type.
