Purpose of change

This aims to tinker with ranged AoE cones to be a bit less wonky against NPCs, fixing one of the many issues affecting it currently.

Fixes #2989

Describe the solution

In ranged_aoe.cpp, converted the hit behavior of execute_shaped_attack to depriciate ranged::hit_with_aoe in favor of using deal_projectile_attack. The idea here is make NPCs caught in the AoE only take a single hit to a random bodypart, with missed_by weighted more in favor of center mass.

This specifically fixes the issue of the function in question dividing the total damage by number of bodyparts, which would turn an amount of damage instantly lethal to a zombie to peppering an NPC with mild annoyance.

Finally, deleted the hit_with_aoe function from ranged.cpp and ranged.h, as execute_ranged_attack was the only function using it.

Describe alternatives you've considered

1. Reworking hit_with_aoe to randomize how many body parts it hits instead of dividing up across all of them. I'm not sure if that'd really be worth it though.
2. Figuring out how to make distance from shooter affect missed_by value instead of making it random.

Testing

1. Compiled and load-tested.
2. Blasted NPCs repeatedly with birdshot, as expected they now only take a conventional hit to a randomly-selected bodypart instead of having damage spread accross the entire body, with it hitting center mass reasonably often.
3. Shot at a crowd of zombies with it, they still take damage as normal, and now the damage varies instead of hitting all of them for exactly 49 damage.
4. Checked affected files for astyle.

Additional context

This doesn't yet re-add AoE to buckshot, since there are other issues with the code not yet sorted out, like gun range not adding to AoE cone length and ammo effect stuff not working right.

This certainly sounds weird, but it might be OK enough.
It would definitely get weird if we had eye hits and similar.

Does it hit the head often enough to matter?

The hit range I gave it is 0.15 to 0.45. While game_constants.h says it needs to be below 0.1 to headshot, in practice NPCs get hit in the head by anything that's equal or less than 0.2: https://github.com/cataclysmbnteam/Cataclysm-BN/blob/main/src/creature.cpp#L820

Though I assume that's just because accuracy_headshot is just the game's name for a hit on a zombie that's considered good enough to call a headshot (faked by damage multipliers against a monster that's technically just a giant torso under the hood), while for creatures with an actual body anything that's accuracy_critical or better hits the head.

EDIT: So very rough math says head will be hit ~19% of the time, random limbs will be hit ~16% of the time, and torso the rest of the time.

while it's not the best solution seems it works so let's try this approach.
