Core/Battlegrounds: Rework queues

* No more copies of Battleground classes
* FreesSlotQueues now have as key the MapId instead of queue id
* Random queues can now popup already busy specific battelgrounds (queues are NOT merged)
* Removed Holiday handling, this should already be handled in BattlegroundMgr::IsBGWeekend
