ui-frame: Add support for style variants
Rather than sharing a single style context between all frames, use a default style and one style per encountered variant. The value of the _GTK_THEME_VARIANT property should determine which style is attached to a particular frame, though for the time being the default style is used for every frame, as the window property cannot be accessed at the time the style is attached. This will be fixed in a later commit. https://bugzilla.gnome.org/show_bug.cgi?id=645355 upstream commit: https://gitlab.gnome.org/GNOME/metacity/commit/04d8135f
