Rollup merge of #126639 - sayantn:amx, r=Amanieu
Add AMX target-features and `x86_amx_intrinsics` feature flag This is an effort towards #126622. This adds support for all 5 target-features for `AMX`, and introduces the feature flag `x86_amx_intrinsics`, which would gate these target-features and the yet-to-be-implemented amx intrinsics in stdarch.
