[Buildroot] [git commit branch/2023.02.x] arch/Config.in.x86: drop AVX512 from alderlake

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=f2cfe1d28c093d2abeef0d86d73022d6c6deea24
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.02.x

Alder Lake CPUs have AVX512 support disabled [0].

To prevent potential issues, remove the AVX512 support advertisement.

This puts Buildroot inline with the GCC options [1].
