[libc++][doc] Use issue labels. During the review of D111166 I had a private discussion with @ldionne to avoid the duplication of the C++2b issues in the Ranges and Format status pages. The main reason for duplicating them is to make it easier to find them. The title of the paper may not always make it clear to which project the paper belongs. This commit removes all LWG-issues from the Ranges and Format status page and adds labels for these issue in the C++20/C++23 issues list. A quick scan revealed there are some issues that are missing a label since they weren't on the ranges issue list. These can be labelled in a separate commit. In that commit I'll also look for issues for the spaceship operator and chrono. Reviewed By: Quuxplusone, ldionne, #libc Differential Revision: https://reviews.llvm.org/D111458

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.

[libc++] Mark LWG3211 as complete: default constructor of tuple<> should be trivial `libc++` has had the guarantee of the default constructor of `tuple<>` being trivial since 405570dc7a95cdf43cdee14b8a9f9c1657a6ad13. Now, the standard mandates it as of LWG3211. So, move the file out of `libcxx/test/libcxx` and into `libcxx/test/std` since it's no longer `libc++`-specific.

[libc++][ranges] implement `std::views::elements_view` `subrange` is also a `tuple-like`. To avoid the add entire `subrange` dependencies to `tuple-like`, we need forward declaration of `subrange`. However, the class template constraints of `subrange` currently requires `__iterator/concepts.h`, which requires `<concepts>`. The problem is that currently `tuple-like` is used in several different places, including libc++ extension for pair constructors. we don't want to add `<concepts>` to pair and other stuff. So this change also created several small headers that `subrange`'s declaration needed inside `__iterator/concepts/` Differential Revision: https://reviews.llvm.org/D136268

[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.

[libc++][spaceship] Implement `lexicographical_compare_three_way` The implementation makes use of the freedom added by LWG 3410. We have two variants of this algorithm: * a fast path for random access iterators: This fast path computes the maximum number of loop iterations up-front and does not compare the iterators against their limits on every loop iteration. * A basic implementation for all other iterators: This implementation compares the iterators against their limits in every loop iteration. However, it still takes advantage of the freedom added by LWG 3410 to avoid unnecessary additional iterator comparisons, as originally specified by P1614R2. https://godbolt.org/z/7xbMEen5e shows the benefit of the fast path: The hot loop generated of `lexicographical_compare_three_way3` is more tight than for `lexicographical_compare_three_way1`. The added benchmark illustrates how this leads to a 30% - 50% performance improvement on integer vectors.

[libc++] Implement the resolutions of LWG3506 and LWG3522. Implement the changes in all language modes. LWG3506 "Missing allocator-extended constructors for priority_queue" makes the following changes: - New allocator-extended constructors for priority_queue. - New deduction guides targeting those constructors. LWG3522: "Missing requirement on InputIterator template parameter for priority_queue constructors". The iterator parameter should be constrained to actually be an iterator type. `priority_queue{1,2}` should be SFINAE-friendly ill-formed. Also, do a drive-by fix in the allocator-extended move constructor: there's no need to do a `make_heap` after moving from `__q.c` into our own `c`, because that container was already heapified when it was part of `__q`. [priqueue.cons.alloc] actually specifies the behavior and does *not* mention calling `make_heap`. I think this was just a copy-paste thinko. It dates back to the initial import of libc++.

[libc++][doc] Use issue labels. During the review of D111166 I had a private discussion with @ldionne to avoid the duplication of the C++2b issues in the Ranges and Format status pages. The main reason for duplicating them is to make it easier to find them. The title of the paper may not always make it clear to which project the paper belongs. This commit removes all LWG-issues from the Ranges and Format status page and adds labels for these issue in the C++20/C++23 issues list. A quick scan revealed there are some issues that are missing a label since they weren't on the ranges issue list. These can be labelled in a separate commit. In that commit I'll also look for issues for the spaceship operator and chrono. Reviewed By: Quuxplusone, ldionne, #libc Differential Revision: https://reviews.llvm.org/D111458

[libc++] LWG 3857: allow `string_view` conversion when only traits vary The `basic_string_view` constructor accepting a contiguous range rejects converting between `basic_string_view` even when only the trait types vary. This prevents conversions for converting from `basic_string_view<C, T1>` and `basic_string<C, T1, A>` to `basic_string_view<C, T2>`. Recently, this constructor was made `explicit`, so there's no reason to really forbid this conversion anymore. Relax the restriction that the trait types need to match in this constructor.
