Following the work done in #19361 this is the cleanup and improvement of the related logic of waypoint management.
Ref 28050f3#18020
(taking the good parts and ignoring the incomplete work)
(cherry picked from commit 7fff83d675)
Today, we're moving UNIT_FLAG_IMMUNE_TO_PC and UNIT_FLAG_IMMUNE_TO_NPC to higher-level abstraction so combat manager can react to it.
New methods on Unit:
- void SetImmuneTo<All/PC/NPC>(apply, keepCombat = false);
- bool IsImmuneTo<All/PC/NPC>() const;
(cherry picked from commit 74af880217)
- Changed self-accessor on GameObjectAI to "me", like UnitAI
- Moved all related functions to AI, now Unit and GameObject have the same function names with identical behaviour
- Remove "OnUpdate" from CreatureScript/GameObjectScript, was never used and we already have AI Update method
- Quest methods no longer return a bool, the return value was used to call the AI version if the ScriptMgr one returned false
- Implemented GameObjectAI::Destroyed hook (was never called), implemented Damaged method
- Rename OnStateChanged to OnLootStateChanged to reflect when it's really called, and created a new hook OnStateChanged that only gets called on GOState change
- Since the functions are now only getting called from AI, made GetAI methods full virtual. (CanSpawn method is anyways going to be used on creatures with AI)
(cherry picked from commit f913f3bb89)

Closes issue #17916
(cherry picked from commit 2b26894eb1)
* Mostly aimed at removing Log/DatabaseEnv includes from other headers
* Fix most packet headers including other packet headers - moved common structures such as ItemInstance to their own files
* Moved SAI function definitions to source files (massive or requiring many different dependencies)
Move all InstanceScript initialization code from Initialize() to the constructor.
InstanceScript::Initialize() is now obsolete, please don't use it anymore. The only reason it's still in the sources is for backward compatibility.
Create ScriptedAIs that require a InstanceScript reference only if the InstanceScript exists, so if these Creatures are in an instance. ScriptedAIs that don't require a InstanceScript reference have not been modified.
This fixes many possible NULL dereference crashes happening when spawning a scripted Creature outside of an instance.
Fixed a GetOwner() and a ToPlayer() NULL dereference crashes too.
