Rollup merge of #97366 - WaffleLapkin:stabilize_array_slice_from_ref, r=dtolnay
Stabilize `{slice,array}::from_ref`

This PR stabilizes the following APIs as `const` functions in Rust `1.63`:
```rust
// core::array
pub const fn from_ref<T>(s: &T) -> &[T; 1];

// core::slice
pub const fn from_ref<T>(s: &T) -> &[T];
```

Note that the `mut` versions are not stabilized as unique references (`&mut _`) are [unstable in const context].
