Refactors obscured (#92779)

## About The Pull Request

Fixes #85028

Obscured flags and covered flags are tracked on carbons, updated as
items are equipped and unequipped. It's that shrimple.

Closes #92760

Just removes the species exception checks for not making sense

Also refactors handcuffs / legcuffs removal. In all of these situations
they were hardcoded when they could easily just use an inventory proc to
work.

## Why It's Good For The Game

Stops a million excessive calls to `check_obscured_slots`

Makes obscured behavior more consistent

Makes obscured behavior easier to use

Cleans up human rendering (There was some cursed stuff before with
render item -> updated obscured -> update body -> cause side effects)

## Changelog

🆑 Melbert
del: Golems which somehow manage to grow wings and somehow manage to
equip something that covers their jumpsuit can no longer fly.
(Seriously, this will not affect anyone)
refactor: Refactored clothing obscurity entirely. Items should be a
loooot more consistent and what covers what, and should update a lot
snappier. As always, report any oddities, like mysteriously disappearing
articles of clothing, hair, or species parts
refactored: Refactored handcuffs and legcuffs a bit, report any odd
situations with cuffs like getting stuck restrained
