Rollup merge of #128221 - calebzulawski:implied-target-features, r=Amanieu
Add implied target features to target_feature attribute See [zulip](https://rust-lang.zulipchat.com/#narrow/stream/208962-t-libs.2Fstdarch/topic/Why.20would.20target-feature.20include.20implied.20features.3F) for some context. Adds implied target features, e.g. `#[target_feature(enable = "avx2")]` acts like `#[target_feature(enable = "avx2,avx,sse4.2,sse4.1...")]`. Fixes #128125, fixes #128426 The implied feature sets are taken from [the rust reference](https://doc.rust-lang.org/reference/attributes/codegen.html?highlight=target-fea#x86-or-x86_64), there are certainly more features and targets to add. Please feel free to reassign this to whoever should review it. r? ``@Amanieu``
