Note that this class was called just `split_view` in the original One
Ranges Proposal and was renamed to `lazy_split_view` by
[P2210](https://wg21.link/p2210).

Reduced the details of the non-chrono formatting information. This has
been shipped and these details part of P0645 which is still documented.
Removing this information keeps the information up-to-date.
Adds the formatters required for the types chrono namespace.

Addresses LWG 3548 which mandates that when shared_ptr is being constructed from a unique_ptr, the unique_ptr's deleter should be moved and not copied.

Changes in [P0896](https://wg21.link/p0896):
- add `disable_sized_sentinel_for`;
- add `iter_move` and `iter_swap`;
- add a `requires` clause to the `operator->`;
- add `iterator_concept`;
- check that the `Iterator` template parameter is a bidirectional
iterator;
- add constraints to all comparison operators;
- change the definitions of `iterator_category`, `value_type`,
`difference_type` and `reference` (changes to `iterator_category` were
already implemented).
Also add a few forgotten things to the `reverse_iterator` synopsis
(notably the spaceship operator).

Fixes LWG3656, "Inconsistent bit operations returning a count".
https://cplusplus.github.io/LWG/issue3656
The fix has been approved for C++23 and left to vendors' discretion
in C++20 (but it sounds like everyone's on the same page that
of course it should be DR'ed back to C++20 too).

The changes from the One Ranges Proposal amount to adding:
- a constructor that takes a `default_sentinel_t` and is equivalent to
the default constructor;
- an `operator==` that compares the iterator to `default_sentinel_t`.
The original proposal defined two overloads for `operator==` (different
argument order) as well as `operator!=`. This has been removed by
[P1614](https://wg21.link/p1614).

`{back,front}_insert_iterator` and `ostream{,buf}_iterator` effectively
fully implement the One Ranges Proposal already, so mark them as done:
- the change to `difference_type` was made by D103273;
- default constructors and the associated default member initializers
were removed by wg21.link/P2325 (implemented by D102468).
Also fix a stale template signature in the `<iterator>` synopsis.
Note that most changes to `strings` and `views.span` from the One Ranges
Proposal are no longer applicable:
- free `begin` and `end` functions taking `basic_string_view` and `span`
were removed by [P1870](http://wg21.link/p1870);
- `span::const_iterator` was removed by [LWG3320](https://cplusplus.github.io/LWG/lwg-defects.html#3320).
