Auto merge of #81238 - RalfJung:copy-intrinsics, r=m-ou-se
directly expose copy and copy_nonoverlapping intrinsics

This effectively un-does https://github.com/rust-lang/rust/pull/57997. That should help with `ptr::read` codegen in debug builds (and any other of these low-level functions that bottoms out at `copy`/`copy_nonoverlapping`), where the wrapper function will not get inlined. See the discussion in https://github.com/rust-lang/rust/pull/80290 and https://github.com/rust-lang/rust/issues/81163.
