[libc++][doc] Updates format status.

[Mordante]

Summary

The paper

• P2286R8 Formatting ranges

is fully implemented modulo its feature test macro. This macro has been
revised by

• LWG3750 Too many papers bump __cpp_lib_format

The new macro depends on

• P2585R0 Improving default container formatting

This paper revises parts of P2286R8 and adds new formatter
specializations. The specialization for debug strings has some wording
issues, which is addresses in this paper

• P2733R0 Fix handling of empty specifiers in std::format

 Improvements and New Features
 -----------------------------
 - Declarations of ``std::c8rtomb()`` and ``std::mbrtoc8()`` from P0482R6 are
   now provided when implementations in the global namespace are provided by
   the C library.
 - Implemented ``<memory_resource>`` header from C++17
 - `D122780 <https://reviews.llvm.org/D122780>`_ Improved the performance of std::sort
