… to die if wearing thermal insulation (tgstation#85401)

## About The Pull Request

When returning to thermal equilibrium, the core temperature and body
temperature seem to get stuck in a feedback loop, causing them to
sometimes get stuck below or above safe limits and kill the player
unless they remove their armor. This fixes that.

Here's a pic of slowly returning to safe temperature after being shot a
bunch by watcher, whereas originally this would kill you if you had too
much thermal insulation.

(Ignore the duplicate var prints, one should be core_skin_change, but
messed it up)
## Why It's Good For The Game
You don't have to remove your armor to stop from being permanently
frozen/hot.

## About The Pull Request
It was only checking for eye protection, since light-sensitives can have
0 or less eye protection even with sunglasses on, this doesn't make
sense.
There is now more redundancy, the same check for blind carbons and
another check for `is_eyes_covered` which takes in account if your eyes
are covered by eyewear or masks.
## Changelog
:cl:
fix: spray can face spraying will no longer work on light-sensitives
with eyewear and people wearing eye covering masks
