When targeting the MSVC ABI, define `_MBCS` by default if the project does not define `_SBCS` or `_UNICODE`. Visual Studio has long defined one of the three character set macros automatically. For consistency, define it when compiling for the MSVC ABI with other generators. Add policy CMP0204 for compatibility. Fixes: #27275
