Due to a bug in LLVM 21, build fails on x86_64 with:
`rustc-LLVM ERROR: Cannot select: intrinsic %llvm.x86.avx512.vpdpbusd.512`.
This has been fixed in Rust's build of LLVM and LLVM 22 [1]
but this is not reflected in nixpkgs' packaging of rustc.
For this reason, we temporarily disable avx512vnni support until this is fixed in nixpkgs.
This might cause a performance penalty, but should not affect correctness.
