Before #47872 `wp_generate_attachment_metadata` was always fired in these cases. Firing it at the end of `wp_update_image_subsizes()` seems to make the most sense and is backwards compatible.

Before #47872 `wp_generate_attachment_metadata` was always fired in these cases. Firing it at the end of `wp_update_image_subsizes()` (when new metadta was generated and additional image sub-sizes created) seems to make the most sense and is backwards compatible.
