All C++20 Ranges papers and LWG issues are done, with the exception of
https://wg21.link/P2210R2 ("Superior String Splitting"), and marked as
such.
All of these were already implemented prior to this patch except bumping
the feature test macro `__cpp_lib_ranges` as required by
https://wg21.link/P2325R3 ("Views should not be required to be default
constructible"). Note that, even though P2325R3 was voted into C++23, it
was voted with a recommendation for vendors to retroactively apply the
change to C++20 (see https://github.com/cplusplus/papers/issues/1007).

This patch is the rebase and squash of three earlier patches.
It supersedes all three of them.
- D47111: experimental monotonic_buffer_resource.
- D47358: experimental pool resources.
- D47360: Copy std::experimental::pmr to std::pmr.
The significant difference between this patch and the-sum-of-those-three
is that this patch does not add `std::experimental::pmr::monotonic_buffer_resource`
and so on. This patch simply adds the C++17 standard facilities, and
leaves the `std::experimental` namespace entirely alone.

During the discussion on the SG-10 mailinglist regarding the format
feature-test macros voted in during the last plenary it turns out libc++
can't mark the format feature-test macro as implemented.
According to
https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations#__cpp_lib_format
the not yet implemented paper
P1361R2 Integration of chrono with text formatting
affects the feature test macro.
Note that P1361R2 doesn't mention the feature-test macro nor is there an
LWG-issue to address the issue. The reporter of the issue didn't recall
where this requirement exactly has been decided.

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.

`__cpp_lib_type_identity` was implemented way back in cf49ccd0 (Clang 8),
probably before the feature-test macro had been settled on.
`__cpp_lib_string_resize_and_overwrite` will be added by D113013 so I didn't add it here.
Fixes#46605.

Since coroutine is merged in C++ standard and the support for coroutine
seems relatively stable. It's the time to move the implementation of
coroutine out of the experimental directory and the std::experimental
namespace. This patch creates header <coroutine> with conformed
implementation with C++ standard. To avoid breaking user's code too
fast, the <experimental/coroutine> header is remained. Note that
<experimental/coroutine> is deprecated and it would be removed in
LLVM15.

`utils/generate_feature_test_macro_components.py` uses the wrong

This patch changes the variant even in pre-C++2b.
It should not break anything, only allow use cases that didn't work previously.
Notes:
`__as_variant` is used in `__visitation::__variant::__visit_alt`, but I haven't used it in `__visitation::__variant::__visit_alt_at`.
That's because it is used only in `__visit_value_at`, which in turn is always used on variant specializations (that's in comparison operators).
