[gnome-control-center/extensible-shell] Add a "shell" property to CcPanel

[Thomas Wood <thos src gnome org>]

commit 027f0e155254e110675faabe132ca4cb02341150

    Add a "shell" property to CcPanel
    
    The shell property on CcPanel allows panels to access the shell they are
    parented in. This means panels can switch the user to a new panel if
    required.
