More clothing use the clothing_traits var. Accessories can use it as well now. (#96455)

## About The Pull Request
While working on some other PR, something caught my eyes. Some clothing
still use the old method of `equipped()` and `dropped()` overrides for
adding traits to the wearer when we already have a clothing_traits
variable to streamline this behavior. This should make short work of
that.

This also improves the accessories code a tiny bit by giving two of the
procs apter names and implements the clothing_traits var onto
accessories as well.

## Why It's Good For The Game
Better, shorter code.

## Changelog
N/A, if something breaks and goes undetected, then we need more unit
tests.
