[mutter/gbsneto/cleanup-x11-from-window-actor: 9/10] window-actor: Remove post_init() vfunc

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 74d75ca1ce674e323ea283e55cf8c5a5efd5deb4
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>

    window-actor: Remove post_init() vfunc
    
    This vfunc was added as a was to work around the convoluted
    initialization process. Now that we figured it out and moved
    the MetaWindowActor-specific initialization to constructed(),
    we can override that.
    
    Remove post_init() and use GObject.constructed() entirely.
