Golem Rework (#74197)

This PR implements this design document:
https://hackmd.io/@Y6uzGFDGSXKRaWDNicSiEg/BkRr176st
Put briefly, this will remove every existing golem subtype and
consolidate golems into a single species with cool new sprites.
NOT implemented from that PR is the ability to eat Telecrystals, I
couldn't come up with an appropriate visual that can stack with the
existing ones, but that should be a reasonably trivial add for a future
artist & developer.

New Golems have a food-based mechanic where their hunger decays pretty
quickly and can only be replenished by eating minerals. They start
moving slower as they get hungrier, until eventually they become
completely immobilised and need to be rescued.
Eating different kinds of minerals will visually change your sprite and
give you a special effect in a similar way to old golems, but temporary.
While transformed, you can't eat any other kind of mineral which would
transform you (but can still consume glass).
To see the full list of effects, look at the hackmd above.

In service of these sprites working I have refactored the
`species/offset_features` feature by killing it and delegating that
responsibility to limbs instead. Rather than applying an offset to items
due to your species, it is due to your weird head or arms. This makes
overall more sense to me, but it inflates the code changes in this PR
somewhat.
It doesn't make a lot of sense to atomise unfortunately because that
code also seemed to be entirely unused until I tried to use it in this
PR, so you wouldn't be able to tell if my changes broke anything. I
might make a downstream sad by doing this.

All of the actual numbers in this PR are made up and only loosely
tested, it will need some testmerges to gather feedback about whether it
sucks or not.

Other relevant changes:
I reworked how bioscrambling works based off bodypart bodytypes, to
automatically exclude golem limbs in either direction. There's really no
way to have those work on humans or vice versa. Organs still fly though.
