Disable AsRef implementations for String's Drain.
...
Since trait implementations cannot be unstable, we should only add them
when the as_str feature gets stabilized. Until then, only `.as_str()` is
available (behind a feature gate).

Mark AsRef impls for String's Drain as stable.

Trait implementations effectively can't be #[unstable].

Add `slice::check_range`
This method is useful for [`RangeBounds`] parameters. It's even been [rewritten](22ee68dc58/src/librustc_data_structures/sorted_map.rs (L214)
) [many](22ee68dc58/library/alloc/src/vec.rs (L1299)
) [times](22ee68dc58/library/core/src/slice/mod.rs (L2441)
) in the standard library, sometimes assuming that the bounds won't be [`usize::MAX`].
For example, [`Vec::drain`] creates an empty iterator when [`usize::MAX`] is used as an inclusive end bound:
```rust
assert!(vec![1].drain(..=usize::max_value()).eq(iter::empty()));
```
If this PR is merged, I'll create another to use it for those methods.
