[meld: 2/3] Build win32 installers with gnome gitlab win32 runners

[Kai Willadsen <kaiw src gnome org>]

    Build win32 installers with gnome gitlab win32 runners
    
    appveyor.yml is removed since it is based on pygobject-win32 which
    is to old for meld 3.19+
    
    Currently pacman invocation isn't perfect since
    it doesn't cache used package versions,
    so build can't be reproduced with same msys2 package versions.
