Removes Clone Damage (#80109)

## About The Pull Request

Does what it says on the tin. We don't have any "special" sources of
clone damage left in the game, most of them are rather trivial so I
bunched them together into this PR.

Notable things removed:
- Clonexadone, because its entire thing was centered around clone damage
- Decloner gun, it's also centered around cloning damage, I couldn't
think of a replacement mechanic and nobody uses it anyways
- Everything else already dealt clone damage as a side (rainbow knife
deals a random damage type for example), so these sources were removed

## Why It's Good For The Game

Consider the four sources of normal damage that you can get: Brute,
Burn, Toxins and Oxygen. These four horsemen of the apocalypse are very
well put together and it's no surprise that they are in the game, as you
can fit any way of damaging a mob into them. Getting beaten to death by
a security officer? Brute damage. Running around on fire? Burn damage.
Poisoned or irradiated? Toxin damage. Suffocating in space? Brute, burn
and oxygen damage. Technically there's also stamina damage but that's
its own ballpark and it also makes sense why we have a damage number for
it.

Picture this now: We have this cool mechanic called "clone pods" where
you can magically revive dead people with absolute ease. We don't want
it to be for free though, it comes at a cost. This cost is clone damage,
and it serves to restrain people from abusing cloning.

Fast forward time a bit and cloning is now removed from the game. What
stays with us is a damage number that is intrinsically tied to the
context of a removed feature. It was a good idea that we had it for that
feature at the time, but now it just sits there. It's the odd one out
from all the other damage types. You can easily explain why your blade
dealt brute damage, but how are you going to fit clone damage into any
context without also becoming extremely specific?

My point is: **clone damage is conceptually a flawed mechanic because it
is too specific**. That is the major issue why no one uses it, and why
that makes it unworthy of being a damage stat.
Don't take my word for it though, because a while ago we only had a
handful of sources for this damage type in the game. And in most of the
rounds where you saw this damage, it came from only one department. It's
not worthwhile to keep it around as a damage number. People also didn't
know what to do with this damage type, so we currently have two ways of
healing clone damage: Cryotubes as a roundstart way of healing clone
damage and Rezadone, which instantly sets your clone damage to 0 on the
first tick. As a medical doctor, when was the last time you saw someone
come in with clone damage and thought to yourself, "Oh, this person has
clone damage, I cannot wait to heal them!" ?

Now we have replacements for these clone damage sources. Slimes? Slime
status effect that deals brute instead of clone. Cosmic heretics? Random
organ damage, because their mechanics are already pretty fleshed out.
Decloning virus? The virus operated as a "ticking timebomb" which used
cloning damage as the timer, so it has been reworked to not use clone
damage. What remains after all this is now a basically unused damage
type. Every specific situation that used clone damage is now relying on
another damage type. Now it's time to put clone damage to rest once and
for all.

Sure, you can technically add some form of cellular degradation in the
future, but it shouldn't be a damage number. The idea of your cells
being degraded is a cool concept, don't get me wrong, but make it a
status effect or maybe even a wound for that matter.

<!-- Argue for the merits of your changes and how they benefit the game,
especially if they are controversial and/or far reaching. If you can't
actually explain WHY what you are doing will improve the game, then it
probably isn't good for the game in the first place. -->

## Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
mark your PRs to prevent unnecessary GBP loss. You can read up on GBP
and it's effects on PRs in the tgstation guides for contributors. Please
note that maintainers freely reserve the right to remove and add tags
should they deem it appropriate. You can attempt to finagle the system
all you want, but it's best to shoot for clear communication right off
the bat. -->

<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
