Core/Dungeon Finder: Minor optimization in handler code

Note: LfgDungeonSet and LfgLockStatusMap were being used without using the existing typedef (to avoid including LFGMgr.h).
Now those functions use a struct as param that is forward declared so still LFGMgr.h is not needed and redefinition of LfgDungeonSet/LfgLockStatusMap is removed.
