Reduce the probabilty of going under the map
(cherry picked from commit 9e0faace9a)
Revert "Core/Entities: Reduce the probability of units dropping under the map (#21322)"
(cherry picked from commit 2dadbda24a)
- Decoupled Unit logic: split of spell critical chance into done (caster bonuses) and taken (target bonuses), this allows to precalculate caster bonuses on aura apply and then check victim's auras on damage/healing calc
- Made static a bunch of methods (they no longer have this pointer because they are now called from periodic handlers which may or may not have an active caster in world)
- Simplified all AuraEffect bonuses into AuraEffect::_amount, no more duplicated code
- Critical chance and whether or not caster is player owned unit (for resilience calcs) is now saved one level upper, on Aura itself (it's impossible as of 3.3.5 to have different effects with different critical chances)
- Minor cleanup of SPELL_DAMAGE_CLASS_NONE and Arcane Potency (#18813) crit handling
Closes#19876

- PvE combat is now always mutual. UNIT_FLAG_IN_COMBAT is backed by actual references to the units we're in combat with.
- PvP combat is now also tracked, and almost always mutual; spells like Vanish and Feign Death can break this rule. That means we can easily determine a list of players we're fighting.
- By extension, IsInCombatWith now has sensible behavior when invoked on nonplayers.
- Threat and combat systems are no longer the same.
- They still have an enforced relationship (threat implies combat - clearing combat clears threat)...
- ...but we can have combat without threat. A creature (with threat list) isn't considered to be engaged until it has an entry on its threat list...
- ...which means we can now faithfully replicate retail engage behavior. Combat on projectile launch - engagement start on projectile impact. Yay for progress!
- AI method refactor, as already ported in 6113b9d - `JustEngagedWith`, `JustEnteredCombat` and `JustExitedCombat`.
- Vehicle threat is now properly pooled on the main vehicle body (fixes#16542).
- Various edge case bug fixes for threat redirects (Misdirection "cancelling" Vigilance and similar).
- Target re-selection is now significantly faster.
- Fixed a ton of other smaller edge case bugs, probably.
Closes#7951 and #19998.

Core/Spell: The giant CastSpell unclusterfucking (that's a word now) of this generation.
- CastSpell now always takes three arguments - target, spellId, and a struct containing extra arguments
- This struct (CastSpellExtraArgs, see SpellDefines.h) serves as a conglomerate of every previous combination of the 20 billion different CastSpell overloads, all merged into one
- It has some great utility constructors - check them out! All of these can be used to implicitly construct the ExtraArgs object.
- A gajillion refactors to make everything behave the way it always has

* Core/Scripts: More fixes in boss Lich King
Fix Valkyr charge spell, they will no longer ignore Z position and become unreachable.
Correct height of Spirit Bomb and added the 3 seconds delay on his explosion.
Set the Trigger inside frostmourne room as active, to avoid problems with reseting the room, e.g: Spirit Bombs not despawning and Wicked Spirits stuck in evade.
Use correct InhabitType for Wicked and Vile Spirits, this avoid a situation where they could spawn falling.

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)
* Combat/Threat rewrite (PR #19930) prep work. Mostly refactors, and a compatibility layer on ThreatManager/HostileReference that allows scripts to be changed already.
