qt_internal_add_executable has some special logic to link static plugins in order to avoid issues with link cycles on exported Qt module targets. This logic does not take into account if a plugin is a default plugin. On windows this caused duplicate symbol linking issues in static super builds, because both qwindows and qdirect2d define a subset of the same symbols. Make sure to only link to default static plugins. This will skip linking to qdirect2d because it's not a default qpa plugin and thus avoid linker issues.
