[gnome-software] Move featured image rendering to css

[Matthias Clasen <matthiasc src gnome org>]

    Move featured image rendering to css
    
    We are constructing custom css for the featured tile anyway,
    and using css for the image lets us use full-size images, and
    rely on css to do the scaling and positioning, instead of manually
    clipping the image.
