Rename classes and files so that they sort where their code is linked,
and move code that is linked inside another TU into that TU's file.

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.
