Rollup merge of #84105 - WaffleLapkin:stabilize_array_from_ref, r=m-ou-se 
stabilize `core::array::{from_ref,from_mut}` in `1.53.0`

I didn't get any response in https://github.com/rust-lang/rust/issues/77101#issuecomment-761831104, so I figured out I can try opening stabilization pr.

---

This PR stabilizes following functions:
```rust
// core::array
pub fn from_ref<T>(s: &T) -> &[T; 1];
pub fn from_mut<T>(s: &mut T) -> &mut [T; 1];
```

Functions are similar to already stabilized `core::slice::{`[`from_ref`](https://doc.rust-lang.org/std/slice/fn.from_ref.html),[`from_mut`](https://doc.rust-lang.org/std/slice/fn.from_mut.html)`}` and were unstable without any problems/questions for a while now.
