VS: Support "Build ISO C++23 Standard Library Modules" option in VS 17.6

New MSVC 17.6 adds a project option called "Build ISO C++23 Standard Library Modules" which creates <BuildStlModules>true/false</BuildStlModules> entry in the vcxproj file and ends up building std.ixx, std.compat.ixx files even though I am exclusively disabling modules using /experimental:module-

We need a way to control this option from CMake.
