[gnome-photos/wip/rishi/collection: 9/45] Support skipping some children while generating the "all" filter



commit c21c1a1d8913b75caaf13922d4d40644e501ff20
Author: Debarshi Ray <debarshir gnome org>

    Support skipping some children while generating the "all" filter
    
    A subsequent commit will add support for GMount-backed sources to
    represent attached devices. These sources shouldn't contribute to the
    SourceManager's "all" filter. This demands finer control over the
    filter generation process.
