monsters: allow pets to wear armor

[mlangsdorf]

Summary

SUMMARY: Features "monsters: allow pets to wear armor"

Purpose of change

Fixes #28627
Allow pets to wear armor.

Describe the solution

Move pet_menu into monexamine.cpp and refactor it.

Create a new bodytype field for monsters that describes the general layout of the monster's body and assign suitable values for most mammals, zombies, fish, insects, and spiders.

Create a new islot_pet_armor which is similar to islot_armor but describes something that can be worn by a pet.

Add a new menu option that allows you to put armor on pets or remove armor from pets wearing armor.

In monster::get_armor_cut(), monster::get_armor_bash(), and monster::get_armor_type(), check for worn armor on the monster and add the armor's protection values.

Alternatives

I considered using item properties, but an islot is more robust.

Notes

zlaves have bodytype human, and should wear non-pet armor, but that's an issue to pursue at a later date.

Someone else should probably go through and add a bunch of recipes and items for various pet armors.

Is that a potential begining for monster wearing stuff instead of spawning them on death or not at all ?

At this time, this is really only intended for pets like tame dogs. As a general solution for monster armor, there are a lot of complications that this does not address.
