So I’m using this feature to provide an adapter between serde::Serialize and fmt::Debug that naturally preserves formatting flags and stays aligned with any changes to std::fmt.

Stabilize the debug_map_key_value feature

RFC: rust-lang/rfcs#2696
Tracking issue: rust-lang#62482

Stabilizes the `debug_map_key_value` feature, which covers:

```rust
impl<'a, 'b> DebugMap<'a, 'b> {
    pub fn key(&mut self, key: &dyn fmt::Debug) -> &mut DebugMap<'a, 'b> {}
    pub fn value(&mut self, value: &dyn fmt::Debug) -> &mut DebugMap<'a, 'b> {}
}
```

These methods are small and self-contained, and are used as the basis for the existing `DebugMap::entry` method, so have been used in the wild for the last 6 months or so.
