[glibmm/glibmm-2-56] Gio::Application: Add property_resource_base_path_string()

[Kjell Ahlstedt <kjellahl src gnome org>]

commit 689ecea19363b0c5f87b2efa99b31eb2170f81a6

    Gio::Application: Add property_resource_base_path_string()
    
    property_resource_base_path() has the wrong return type, bool instead of
    std::string. It can't be fixed without breaking API/ABI. For now, deprecate
    property_resource_base_path() and add hand-coded
    property_resource_base_path_string() with the correct type. Bug 787496
