Most operations where strips are duplicated use `SEQ_animation` API, which handles keyframe animation. Now drivers are handled as well. When group of strips is duplicated and driver references other strip, it will still reference original strip. However, this is much better, than previous behavior, when strip duplication results in "transfer" of driver from original strip to duplicated one. Fixes T104141
