src/gui: Remove QT_WA and non-Unicode code paths, dropping Win9x and NT support

Also - Make winPeekMessage() & winPostMessage() obsolete
     - FlashWindowEx, IsValidLanguageGroup functions no longer resolved
       dynamically (available on >= Windows 2000)
     - LoadIcon/LoadCursor -> LoadImage w/LR_SHARED for system
       icons/cursors
     - qsystemtrayicon_win: use Shell_NotifyIconGetRect if available
       (Windows 7)
