Rollup merge of #87729 - adamgemmell:dev/deprecate-crypto, r=Amanieu

Remove the aarch64 `crypto` target_feature

The subfeatures `aes` or `sha2` should be used instead.

This can't yet be done for ARM targets as some LLVM intrinsics still require `crypto`.

Also update the runtime feature detection tests in `library/std` to mirror the updates in `stdarch`. This also helps https://github.com/rust-lang/rust/issues/86941
