Windows is heading toward making UTF-8 the preferred MBCS. As CMake's internal encoding, `UTF-8` is effectively equivalent to `NONE`, which was CMake's behavior prior to 3.15's accidental change to `AUTO`. Behavior of `ENCODING UTF-8` is independent of CMake's internal encoding, making it in principle a better default than `NONE`. Add policy CMP0176 for compatibility and to document the default's history. Fixes: #26262
