Heli AI weapon handling from Bodyguard Squads

/*
This function allows any ped on an attack heli to use its weapons against the enemies the ped is fighting.
Pasted here as used in https://www.gta5-mods.com/scripts/bodyguard-squads.
Call on tick, providing the ped that is on an heli that has weapons.
Lacks multiweapon handling for now, they only use the default weapon (Minigun for buzzard/annihilator, explosive rounds for Valk/Savage).
