snd: move sound actions and AIs to KingSystem/Sound

They link with KingSystem/Sound (0x7100fe8b54-0x7101060ed4) as sorted
Action/AI passes of their own. The three area tag actions keep their
game base AreaTagAction, which links in the Game/Actor/Area block.

(AI assisted using Claude Fable 5.1 and Claude Opus 5.5)
