    window-wayland: Set transient and window type on manage() for popups
    
    Doing this on manage() allows the common MetaWindow initialization to
    do the right thing for popups like setting skip_taskbar and
    skip_pager.
    
    In particular this avoids gnome-shell's app tracker to create a new
    ShellApp instance for every popup.
