Auto merge of rust-lang#110019 - jplatte:jplatte/stabilize-is-some-and, r=Amanieu

Stabilize is_some_and

This stabilizes the following public API:

```rust
impl<T> Option<T> {
    pub fn is_some_and(self, f: impl FnOnce(T) -> bool) -> bool;
}

impl<T, E> Result<T, E> {
    pub fn is_ok_and(self, f: impl FnOnce(T) -> bool) -> bool;
    pub fn is_err_and(self, f: impl FnOnce(E) -> bool) -> bool;
}
```

Closes rust-lang#93050 (tracking issue).
