vkconfig: 150% scaling on Windows makes font looks ugly

Using:
```
    qputenv("QT_AUTO_SCREEN_SCALE_FACTOR", "0");
    qputenv("QT_SCALE_FACTOR", "1.0");
    qputenv("QT_ENABLE_HIGHDPI_SCALING", "0");

    QApplication app(argc, argv);
    app.setHighDpiScaleFactorRoundingPolicy(Qt::HighDpiScaleFactorRoundingPolicy::Round);
    app.setStyle("fusion");
```

The font looks fine but the UI needs to aumatically scale based on the font size...
