[libadwaita/wip/exalm/osd] stylesheet: .osd refinements

[Alexander Mikhaylenko <alexm src gnome org>]

commit a769cf3cf66db327aa7abefb64ce7a71a706c7fc
Author: Alexander Mikhaylenko <alexm gnome org>
Date:   Wed Dec 1 19:54:39 2021 +0500

    stylesheet: .osd refinements
    
    Make checks, links, switches, progress bars, scales and level bars use
    white accent instead, also change their focus rings.
    
    Since focus rings are also used on button.card, make a proper .osd card
    style as well.
    
    Fixes https://gitlab.gnome.org/GNOME/libadwaita/-/issues/245
