Fix [#36422] Trimmed audio files (hard cut only) in a metastrip have their trim removed

Meta sound update (seq_update_sound_bounds_recursive_rec) was not taking into account hard trim (anim_startofs) when setting sound's start, while default sound strip update (sound_move_scene_sound_defaults) did... This could use some refactor, though, with a single func used in both cases, to avoid such issue.

Also added soft trim to sound panel, only hard one was available.
