Auto merge of #132717 - RalfJung:rustc_safe_intrinsic, r=compiler-errors

remove support for rustc_safe_intrinsic attribute; use rustc_intrinsic functions instead

This brings us one step closer towards removing support for `extern "rust-intrinsic"` blocks, in favor of `#[rustc_intrinsic]` functions.

Also move `#[rustc_intrinsic]` under the `intrinsics` feature gate, to match the `extern "rust-intrinsic"` style.
