Brad King 30139913e9 VS: Restore support for mixing C++23 and C in one target with clang-cl
Since commit 474eafe28c (clang-cl: Add support for C++23, 2024-09-13,
v3.31.0-rc1~97^2) we use a Clang-specific flag to enable C++23 since
`clang-cl` has no `-std:c++23` flag, and `-std:c++latest` may enable an
even newer version of C++.  However, in `.vcxproj` files there is no way
to express a target-wide `-clang:-std=c++23` flag for only C++ sources
when the target also has C sources.  Add a special case to map back to
`-std:c++latest` for targets with C++23 and C together.

Fixes: #26508

CMake Tests Directory
*********************

This directory contains the CMake test suite.
See also the `CMake Testing Guide`_ and the `CMake Source Code Guide`_.

.. _`CMake Testing Guide`: ../Help/dev/testing.rst
.. _`CMake Source Code Guide`: ../Help/dev/source.rst

Many tests exist as immediate subdirectories, but some tests
are organized as follows.

* ``CMakeLib/``:
  Source code, used for tests, that links to the ``CMakeLib`` library
  defined over in ``Source/``.

* ``CMakeOnly/``:
  Deprecated.  Tests that run CMake to generate a project but not build it.
  Superseded by ``Tests/RunCMake/``.

* ``Find*/``:
  Tests for specific find modules that can only be run on machines with
  the corresponding packages installed.  They are enabled in
  ``CMakeLists.txt`` by undocumented options used on CI builds.

* ``Module/``:
  Tests for specific CMake modules.

* ``RunCMake/``:
  Tests that run CMake and/or other tools while precisely checking
  their return code and stdout/stderr content.  Useful for testing
  error cases and diagnostic output.

  See `RunCMake/README.rst`_.
