Code Review

This pull request disables the Renormalize and RenormalizeNaive routing methods for TRT-LLM per-tensor FP8 MoE by commenting them out. This is a temporary measure to address accuracy issues as noted in the associated issue. The change is clear, well-commented, and appears to be a reasonable and safe approach to mitigate the bug. I have no further recommendations.
