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).

This reverts commits a30a7948d and 5d1c1a243, which broke the LLDB
data formatters tests because they build with modules in C++11 mode.

`{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Proposal are no longer applicable: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).

This includes an experimental workaround for
LWG3664 "LWG3392 broke std::ranges::distance(a, a+3)",
but the workaround may be incomplete, I'm not sure.
This should be re-audited when LWG3664 is actually adopted,
to see if we need to change anything about our implementation.

Each "Nothing To Do" issue only changed nits in the English wording,
not anything to do with the code.
Each "Complete" issue was completed already, as far as I can tell.
I tried to err on the side of caution: I didn't mark a few issues
whose P/Rs were very invasive and would take time to verify, and I
didn't mark a lot of issues involving features we haven't even started
yet.

The tests for these are just copy-pasted from the tests for std::{strong,weak,partial}_order,
and then I added an extra clause in each (test_2()) to test the stuff that's not just the same
as std::*_order.
This also includes the fix for https://wg21.link/LWG3465 (which falls naturally out of the
"you must write it three times" style, but I've added test cases for it also).
There is an action item here to go back and give good diagnostics for SFINAE failures
in these CPOs. I've filed this as https://github.com/llvm/llvm-project/issues/53456 .

Fixed in counted_iterator and transform_view::iterator.
The LWG issue also affected elements_view::iterator, but we haven't
implemented that one yet, and whoever does implement it will get
the fix for free if they just follow the working draft's wording.
Drive-by stop calling `.base()` on test iterators in the test,
and improve the transform_view::iterator/sentinel tests.
