openblas: disable AVX512, make optional

Browse Source 
This effectly reverts 383075f38b94b25ff30ec68a1bb19b35dc9ce4e8.

Some AVX512 optimized kernels seem to be broken in openblas.
See https://github.com/NixOS/nixpkgs/issues/124250.

(cherry picked from commit 5946bc724fe4f7f37ba907ae01d851f070fc97e0)
