detects redundant imports that can be eliminated.
for #117772 :
In order to facilitate review and modification, split the checking code and
removing redundant imports code into two PR.

Clarify behavior of inclusive bounds in BTreeMap::{lower,upper}_bound
It wasn’t quite clear to me how these methods would interpret inclusive bounds so I added examples for those.

Remove redundant example of `BTreeSet::iter`
The usage and that `Values returned by the iterator are returned in ascending order` are already demonstrated by the other example and the description, so I removed the useless one.

Not useful, for there is just a single example

Our `Cursor::peek_prev` and `CursorMut::peek_prev` must agree
on how to behave when they are called on the "null element".

Make sure that some stdlib method signatures aren't accidental refinements
In the process of implementing https://rust-lang.github.io/rfcs/3245-refined-impls.html, I found a bunch of stdlib implementations that accidentally "refined" their method signatures by dropping (unnecessary) bounds.
This isn't currently a problem, but may become one if/when method signature refining is stabilized in the future. Shouldn't hurt to make these signatures a bit more accurate anyways.
NOTE (just to be clear lol): This does not affect behavior at all, since we don't actually take advantage of refined implementations yet!

Remove some unneeded imports / qualified paths

Implement Default for some alloc/core iterators
Add `Default` impls to the following collection iterators:
* slice::{Iter, IterMut}
* binary_heap::IntoIter
* btree::map::{Iter, IterMut, Keys, Values, Range, IntoIter, IntoKeys, IntoValues}
* btree::set::{Iter, IntoIter, Range}
* linked_list::IntoIter
* vec::IntoIter
and these adapters:
* adapters::{Chain, Cloned, Copied, Rev, Enumerate, Flatten, Fuse, Rev}
For iterators which are generic over allocators it only implements it for the global allocator because we can't conjure an allocator from nothing or would have to turn the allocator field into an `Option` just for this change.
These changes will be insta-stable.

Global implements Default so we can use that as bound for all allocators
|
|
|
|
This way one can `mem::take()` them out of structs or #[derive(Default)] on structs containing them.
These changes will be insta-stable.

|
|
This is a prerequisite for cursor support for `BTreeMap`.

Test leaking of BinaryHeap Drain iterators
Add test cases about forgetting the `BinaryHeap::Drain` iterator, and slightly fortifies some other test cases.
Consists of separate commits that I don't think are relevant on their own (but I'll happily turn these into more PRs if desired).

Stabilize map_first_last
Stabilizes the following functions:
```Rust
impl<T> BTreeSet<T> {
pub fn first(&self) -> Option<&T> where T: Ord;
pub fn last(&self) -> Option<&T> where T: Ord;
pub fn pop_first(&mut self) -> Option<T> where T: Ord;
pub fn pop_last(&mut self) -> Option<T> where T: Ord;
}
impl<K, V> BTreeMap<K, V> {
pub fn first_key_value(&self) -> Option<(&K, &V)> where K: Ord;
pub fn last_key_value(&self) -> Option<(&K, &V)> where K: Ord;
pub fn first_entry(&mut self) -> Option<OccupiedEntry<'_, K, V>> where K: Ord;
pub fn last_entry(&mut self) -> Option<OccupiedEntry<'_, K, V>> where K: Ord;
pub fn pop_first(&mut self) -> Option<(K, V)> where K: Ord;
pub fn pop_last(&mut self) -> Option<(K, V)> where K: Ord;
}
```

Since `len` and `is_empty` are not const stable yet, this also
creates a new feature for them since they previously used the same
`const_btree_new` feature.

The doc link from `DedupSortedIter` to `BTreeMap::bulk_build_from_sorted_iter` was broken when building internal documentation,

BTree: evaluate static type-related check at compile time
`assert`s like the ones replaced here would only go off when you run the right test cases, if the code were ever incorrectly changed such that rhey would trigger. But [inspired on a nice forum question](https://users.rust-lang.org/t/compile-time-const-generic-parameter-check/69202), they can be checked at compile time.
