Rollup merge of #74874 - ssomers:btree_cleanup_8, r=Mark-Simulacrum 
BTreeMap: define forget_type only when relevant

Similar to `forget_node_type` for handles.
No effect on generated code, apart maybe from the superfluous calls that might not have been optimized away.

Rollup merge of #74762 - ssomers:btree_no_root_in_remove_kv_tracking, r=Mark-Simulacrum 
BTreeMap::drain_filter should not touch the root during iteration

Although Miri doesn't point it out, I believe there is undefined behaviour using `drain_filter` when draining the 11th-last element from a tree that was larger. When this happens, the last remaining child nodes are merged, the root becomes empty and is popped from the tree. That last step establishes a mutable reference to the node elected root and writes a pointer in `node::Root`, while iteration continues to visit the same node.

This is mostly code from #74437, slightly adapted.

BTreeMap: remove into_slices and its unsafe block

A small tweak to make BTreeMap code shorter and less unsafe.

5ef872f961 Auto merge of #74605 - rust-lang:vec-leak, r=Amanieu 
Stabilize Vec::leak as a method

Closes https://github.com/rust-lang/rust/issues/62195

The signature is changed to a method rather than an associated function:

```diff
-pub fn leak<'a>(vec: Vec<T>) -> &'a mut [T]
+pub fn leak<'a>(self) -> &'a mut [T]
```

The reason for `Box::leak` not to be a method (`Deref` to an arbitrary `T` which might have its own, different `leak` method) does not apply.

b5eae9c44d Auto merge of #74373 - lcnr:array_chunks, r=withoutboats 
add `slice::array_chunks` to std

Now that #74113 has landed, these methods are suddenly usable. A rebirth of #72334

Tests are directly copied from `chunks_exact` and some additional tests for type inference.

r? @withoutboats as you are both part of t-libs and working on const generics. closes #60735

Rollup merge of #74782 - vorner:weak-into-raw-cnt-doc, r=dtolnay 
Don't use "weak count" around Weak::from_raw_ptr

As `Rc/Arc::weak_count` returns 0 when having no strong counts, this
could be confusing and it's better to avoid using that completely.

Closes #73840.
