On Windows, the only reliable way to read/write Unicode text from/to a Console is to use `ReadConsoleW` and `WriteConsoleW` and convert from/to wide-character encoding. When `cin`, `cout`, and/or `cerr` are attached to a Windows Console, use a custom C++ `streambuf` to handle the I/O. This will replace KWSys ConsoleBuf, whose implementation is more complex to support narrow output streams on Windows non-UTF-8 narrow encodings. We only need to support UTF-8. Issue: #26924
