Rollup merge of #140389 - sayantn:avx512fp16, r=Amanieu
Remove `avx512dq` and `avx512vl` implication for `avx512fp16`

According to Intel, `avx512fp16` requires only `avx512bw`, but LLVM also enables `avx512vl` and `avx512dq` when `avx512fp16` is active. This is relic code, and will be fixed in LLVM soon. We should remove this from Rust too asap, especially before the stabilization of AVX512
