Research direction

Start by inspecting the cpufeatures crate and its existing target-feature support, then compare the unchecked items with rust-lang/rust#126617, rust-lang/rust#126639, and rust-lang/rust#128192. Done means the newly listed x86 and AArch64 target features are supported consistently with the already added sha512, sm3, and sm4 features.
