Subject: CMakeLists: Force C++20 on MSVC due to conflicts with C++23 modules

The latest version of MSVC STL brings C++23 standard library modules, which conflict with precompiled headers.
Disabling with /experimental:module- has no effect, so force C++20 in the meantime while we wait for module support in other compilers.
