9e5c293492 [libc++] Removes __cpp_lib_monadic_optional.
P0798R8 "Monadic operations for std::optional" has been implemented, so
this LWG issue can be adopted.

During review it was discovered another paper bumped the macro. The
part affecting optional of this paper is done, the variant isn't. The
status page is updated to reflect the current state.

Implements
- LWG 3621 Remove feature-test macro __cpp_lib_monadic_optional

Updates status of
- P2231R1 Missing constexpr in std::optional and std::variant

719bf2d9d9 [runtimes] Officially deprecate the legacy testing configuration system
Add a warning and tweak the release note to explain that the deprecation
targets libc++, libc++abi and libuwnind as well.

Also, as a fly-by, ensure that our CI runs the legacy testing configuration
for libc++, libc++abi and libunwind. This doesn't matter too much since
it's deprecated, but we might as well test it properly.

4d8268fbf4 [libc++][format] Improve format-arg-store.
This optimizes the __format_arg_store type to allow a more efficient
storage of the basic_format_args.

It stores the data in two arrays:
- A struct with the tag of the exposition only variant's type and the
  offset of the element in the data array. Since this array only depends
  on the type information it's calculated at compile time and can be
  shared by different instances of this class.
- The arguments converted to the types used in the exposition only
  variant of basic_format_arg. This means the packed data can be
  directly copied to an element of this variant.

The new code uses rvalue reference arguments in preparation for P2418.
The handle class also has some changes to prepare for P2418. The real
changed for P2418 will be done separately, but these parts make it
easier to implement that paper.

Some parts of existing test code are removed since they were no longer
valid after the changes, but new tests have been added.

Implements parts of:
- P2418 Add support for std::generator-like types to std::format

Completes:
- LWG3473 Normative encouragement in non-normative note

Depends on D121138

a80e65e00a [libc++] Overhaul how we select the ABI library
This patch overhauls how we pick up the ABI library. Instead of setting
ad-hoc flags, it creates interface targets that can be linked against by
the rest of the build, which is easier to follow and extend to support
new ABI libraries.

This is intended to be a NFC change, however there are some additional
simplifications and improvements we can make in the future that would
require a slight behavior change.

30194d45f0 [libcxx] [ci] Add a i386 Windows configuration to CI
Adding a mingw based config is easy in the current CI environment
(where we can just choose the different target by calling
`i686-w64-mingw32-clang`), while adding a clang-cl based config would
require setting up different environment variables pointing to the
i386 library directory.

Just adding one config (DLL) instead of exhaustively testing both
(DLL and static) as very few tests would differ in practice, to keep
the CI load reasonable.

- add zip_view and views::zip for C++23
- added unit tests
- implemented section 5.6 (zip) in P2321R2

I used clang-format to format the files but they look nothing like the rest of the code base. Manually indenting each line to match the styles sounds like an impossible task. Is there any clang-format file which can format it reasonable similar to the rest of the code base so that I can manually format the rest lines that look weird?
