    [MSPAINT] Don't allow to set image as wallpaper if it has the wrong format
(#4924)
    
    CORE-18661
    
    Our Paint allows user to try to set a .ico file as a wallpaper, which isn't
possible. Different Windows versions have different behaviour, so it was decided that the
simplest fix would be to just grey out "Set as wallpaper" buttons as in 2K3 (See
the Jira ticket).
