[libc++] Deprecate the _LIBCPP_ENABLE_CXX20_REMOVED_ALLOCATOR_MEMBERS macro (#77692)

As described in #69994, using the escape hatch makes us non-conforming
in C++20 due to incorrect constexpr-ness. It also leads to bad
diagnostics as reported by #63900. We discussed the issue in the libc++
monthly meeting and we agreed that we should deprecate the macro in LLVM
18, and then remove it in LLVM 19 since it causes too many problems.

This patch does the first part of this -- it deprecates the macro.

Fixes #69994
Fixes #63900
Partially addresses #75975

The LLVM Compiler Infrastructure

OpenSSF Scorecard libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
