feat(Core/GameObjects): Instance gameobject save data implementation (#11113)

* fix(Core): Save gameobject state on instances

Currently, azerothcore doesn't save gameobject states on instances.
Whenever there's a re-start or crash, the instance's gameobjects and
their states aren't saved, producing un-wanted behaviours and blocking instances at times.

Implemented CRUD for new table `instance_saved_data` that holds the states of gameobjects.

- When worldserver launches and gameobjects are loaded, this will check
  if this object's state exists on the DB and sets the previous state.
- On instance deletion (reset) these states are also removed based on
  the instance ID.
- Whenever a gameobject state changes inside a dungeon or raid, we save
  on the database the set state.

* Select query to synchronous and used FindMap()

* loading gameobject states on create

* reseting instance saved data

* missing reset methods and on create state

* database structure

* Update src/server/game/Entities/GameObject/GameObject.cpp
