[gnome-software] gs-app-row: Add some properties so they can be set at construction time

[Philip Withnall <pwithnall src gnome org>]

commit a289576a52bb900569722aa8676f7212e1ad2cfd

    gs-app-row: Add some properties so they can be set at construction time
    
    This should speed up the process of setting up a `GsAppRow`, since it
    will (in a following commit) allow the ‘refresh’ calls at construction
    time to be coalesced.
