Qt 6/Windows Desktop: Update code determining the system default fonts

    Description

      The code determining default fonts in the Windows font databases uses deprecated API/old legacy fonts.

      • QWindowsFontDatabase::systemFont(), QWindowsFontDatabase::systemDefaultFont() : This currently uses GetStockObject(DEFAULT_GUI_FONT) to obtain the default GUI font (typically "MS Shell Dlg 2, 8pt"). This has been long deprecated; the message font of the NONCLIENTMETRICS structure obtained by SystemParametersInfo(SPI_GETNONCLIENTMETRICS) should be used instead (see QWindowsTheme::refreshFonts(), typically "Segoe UI, 9pt"), which is larger. Needs to be updated since bogus font sizes are returned in High DPI Multimonitor setups.
      • The console font is outdated (see "Change default Windows monospaced font to Consolas/Lucida Console" https://codereview.qt-project.org/#/c/175168/ ) . This might be applied to Qt 5 since the optical difference is marginal?
