core: rework game stack state mechanism
The current model was fundamentally broken as the state could continue its
execution when calling mlk_game_pop from itself (e.g. in update).
The current model uses a sjlj mechanism with mlk_game_push/pop being disallowed
in special state function like end, finish, suspend.
