gh-77532: Minor tweaks to allow compiling with PlatformToolset=ClangCL on Windows (GH-101352)
To use this, ensure that clang support was selected in Visual Studio Installer, then set the PlatformToolset environment variable to "ClangCL" and build as normal from the command line.
It remains unsupported, but at least is possible now for experimentation.
