[libcxx] Provide locale conversions to tests through lit substitution (#105651)

There are 2 problems today that this PR resolves:

libcxx tests assume the thousands separator for fr_FR locale is x00A0 on
Windows. This currently fails when run on newer versions of Windows (it
seems to have been updated to the new correct value of 0x202F around
windows 11. The exact windows version where it changed doesn't seem to
be documented anywhere). Depending the OS version, you need different
values.

There are several ifdefs to determine the environment/platform-specific
locale conversion values and it leads to maintenance as things change
over time.

This PR includes the following changes:

- Provide the environment's locale conversion values through a
  substitution. The test can opt in by placing the substitution value in a
  define flag.
- Remove the platform ifdefs (the swapping of values between Windows,
  Linux, Apple, AIX).

This is accomplished through a lit feature action that fetches the
environment's locale conversions (lconv) for members like
'thousands_sep' that we need to provide. This should ensure that we
don't lose the effectiveness of the test itself.

In addition, as a result of the above, this PR:

- Fixes a handful of locale tests which unexpectedly fail on newer
  Windows versions.
- Resolves 3 XFAIL FIX-MEs.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices 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.

Getting in touch
