Follow-up to #75932. Since these icons are only used by the export plugin, it makes sense to move them and generate the headers there. The whole `detect.is_active()` logic seems to be a leftover from before times, as far back as 1.0-stable it already wasn't used for anything. So I'm removing it and moving the export icon generation to `platform_methods`, where it makes more sense.
