Validate exhaustive autotuning for FP8 Inductor templates

Summary:
X-link: pytorch/pytorch#161442

Validate exhaustive autotuning for FP8 Inductor templates: scaled MM templates require `block_k >= 32`. Before, exhaustive autotuning defaulted to a limited set of autotuning configs, as limitations for exhaustively autotuning on FP8 shapes had not been tested.
