Allows to pass the horizontal facing/yaw and vertical angle/pitch of the carrier projectile to warheads for further use. Add ImpactPosition to WarheadArgs InflictDamage doesn't pass the impact pos directly, and the very point of WarheadArgs is to avoid adding more and more arguments to the warhead methods.
