bors da1e0d1d75 Auto merge of #116218 - tgross35:const-maybe-uninit-zeroed, r=dtolnay ...

Stabilize `const_maybe_uninit_zeroed` and `const_mem_zeroed`

Make `MaybeUninit::zeroed` and `mem::zeroed` const stable. Newly stable API:

```rust
// core::mem
pub const unsafe fn zeroed<T>() ->;

impl<T> MaybeUninit<T> {
    pub const fn zeroed() -> MaybeUninit<T>;
}
```

This relies on features based around `const_mut_refs`. Per `@RalfJung,` this should be OK since we do not leak any `&mut` to the user.

For this to be possible, intrinsics `assert_zero_valid` and `assert_mem_uninitialized_valid` were made const stable.

Tracking issue: #91850
