Bug 1965779 - Remove GTK iconSize / iconState from icon URI. r=stransky,settings-reviewers

Icon state is now unused (and wasn't used anyhow). Icon sizes are
hardcoded in GTK as per: https://docs.gtk.org/gtk3/enum.IconSize.html

So we can migrate the few usages left to the actual sizes, and remove
the supporting code.
