[gnome-music/wip/mschraal/window-template: 5/7] playertoolbar: Shift visibility logic around

    playertoolbar: Shift visibility logic around
    
    Move most of the PlayerToolbar visibility logic to Window, however on
    startup the toolbar is not shown. For that special case there is some
    additional logic in Window and PlayerToolbar itself.
    This also removes one init argument from PlayerToolbar.
