Refactors NODROP flag into TRAIT_NODROP (#42109)

* Refactors NODROP flag into TRAIT_NODROP 🆑 coiax fix: Anti-drop implants can no longer be used to drop objects that they were not responsible for sticking to a person's hand. fix: Backfiring with a Barnyard spellbook will now play a spooky horse sound. refactor: Refactors the way that "NODROP" items work to a new system, there should be no change in functionality. /🆑 Various items in the codebase were doing weird hoop jumps in order to preserve the nodrop flag's state when it also wanted to change it, so I moved it to a trait system. I may have gone overboard with the type of unique trait sources, but those can be changed later. My long term plan is make a general "CURSED" nodrop origin, which means you can unlock cursed items by being hit with a bolt of door opening or something. But that's for another PR, this has no functionality changes, apart from some slightly modified descriptions on cursed masks. - Removed a bunch of redundant voice changing code for all the voice changing animal masks, used two new clothing flags for this purpose. - Also refactored a bit the animal masks, making new cursed subtypes that play the sound when created. * Drop location
