[gnome-photos/wip/rishi/collection: 13/24] Add Filterable::is_search_criterion

[Debarshi Ray <debarshir src gnome org>]

commit 1775ed6591e2c71a71bdc4ca3da12d505ad2e691
Author: Debarshi Ray <debarshir gnome org>
Date:   Thu Jan 11 18:42:28 2018 +0100

    Add Filterable::is_search_criterion
    
    Not every instance of a Filterable implementation is supposed to be
    offered as a search criterion through the Dropdown. So far, this
    distinction was simple - all instances of a certain implemention were
    either offered or not, and determined by Dropdown through the
    corresponding BaseManager.
    
    However, the introduction of GMount-backed PhotosSources demands finer
    control. A GMount-backed Source shouldn't be presented through the
    Dropdown, while other Sources should be.
    
    This method is meant to address that.
