Rollup merge of #138275 - folkertdev:expose-is-s390x-feature-detected, r=Mark-Simulacrum

expose `is_s390x_feature_detected!` from `std::arch`

tracking issue: https://github.com/rust-lang/rust/issues/135413
implementation: https://github.com/rust-lang/stdarch/pull/1699 (more features added in https://github.com/rust-lang/stdarch/pull/1720)

This macro was part of the recent `stdarch` synchronization, but not yet exposed via `std::arch`.
