[Tizen](Vector) Finalize VectorThread if application terminated + Wait all lottie task completed at destory time

Let we don't do any additional progress after application terminated.

Also, let we keep the VectorAnimationThread lifetime until all
working VectorAnimationTask are completed.

Since that task use VectorAnimationThread as reference, we cannot release
the memory of VectorAnimationManager memory. So just call finalize API.
