The ThemeIcon enum provides symbolic names of icons for which most
engines provide an icon. We couldn't find a matching icon for several of
the XDG icon names, so remove those enum values for which we don't have
at least two matches.
Also remove names that are too specific for a desktop environment,
like icons for certain applications or system-wide actions.
Pick-to: 6.7
