[mutter/wip/nielsdg/use-g-declare-interface: 1/2] clutter: Content: use G_DECLARE_INTERFACE()



commit 1007aa40f25b0cc7b2250cb21582f0876f060952

    clutter: Content: use G_DECLARE_INTERFACE()
    
    It cuts away a bit of the GObject boilerplate, gives us support for
    `g_autoptr`, and removes the typedef hack inside clutter-content.c.
