Core/Mechanics: Fix prevent fleeing + fear

Closes #9754

Players should never have been affected by SPELL_AURA_PREVENTS_FLEEING in the first place.
Curse of Recklessness will no longer prevent Fear effects, only prevent NPCs from fleeing (e.g. at low health).
Judgement of Justice will no longer prevent Fear effects, but will only prevent NPCs from fleeing (e.g. at low health).

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.

Core/Spells: Always add threat for spells from spell_threat table, not only if target was hit. Unsuccessful cast results in 0 threat added instead of the full amount and creating threat list entry for caster. This fixes various exploits with taunt spells bugging out scripts due to taunt immunity/passive state (creatures would immediately evade resetting script state if no entries were present on threat list - entry with no threat is not the same as no entry)
