Rollup merge of #140825 - rs-sac:ext, r=workingjubilee

Add Range parameter to `BTreeMap::extract_if` and `BTreeSet::extract_if`

This new parameter was requested in the btree_extract_if tracking issue:  https://github.com/rust-lang/rust/issues/70530#issuecomment-2486566328

I attempted to follow the style used by `Vec::extract_if`.

Before:

```rust
impl<K, V, A: Allocator + Clone> BTreeMap<K, V, A> {
    #[unstable(feature = "btree_extract_if", issue = "70530")]
    pub fn extract_if<F>(&mut self, pred: F) -> ExtractIf<'_, K, V, F, A>
    where
        K: Ord,
        F: FnMut(&K, &mut V) -> bool;
}
```

After:

```rust
impl<K, V, A: Allocator + Clone> BTreeMap<K, V, A> {
    #[unstable(feature = "btree_extract_if", issue = "70530")]
    pub fn extract_if<F, R>(&mut self, range: R, pred: F) -> ExtractIf<'_, K, V, R, F, A>
    where
        K: Ord,
        R: RangeBounds<K>,
        F: FnMut(&K, &mut V) -> bool;
}
```

While I believe I have adjusted all of the necessary bits, as this is my first attempt to contribute to Rust, I may have overlooked something out of ignorance, but if you can point out any oversight, I shall attempt to remedy it.
