7b0650d5 - Back out "[static-runtime] change the backend for permute_copy" (#89463)

Back out "[static-runtime] change the backend for permute_copy" (#89463) Summary: This permute copy change seems to be causing huge regressions on machines without AVX512. Revert to mitigate. This shouldn't be problematic since the improvement from changing it was super small anyways.
