Revert "Add test coverage to tf32 in max autotune mm configs (pytorch#161545)"

This reverts commit e9d34b2.

Reverted pytorch#161545 on behalf of https://github.com/atalman due to inductor/test_max_autotune.py::TestMaxAutotuneRemoteCache::test_get_mm_configs_float32_precision_ieee [GH job link](https://github.com/pytorch/pytorch/actions/runs/17283985553/job/49058214260) [HUD commit link](https://hud.pytorch.org/pytorch/pytorch/commit/e9d34b2438d65d6d16109e2416f3698de20f85c2) ([comment](pytorch#161545 (comment)))
