Disassemble finished and unfinished Golem shells with a crowbar (Not Golem species) (#95167)

## About The Pull Request

Lets players disassemble unfinished Golem shells in `lavaland_ruin_code`
and finished Golem shells in `golem_roles` by using a crowbar on them.
Both dropping a single adamantine on successful deconstruction, with the
finished shell dropping half of whatever was originally used to create
it.

## Why It's Good For The Game

If a Xenobiologist is able to set up a golem factory. (Chemistry IV drip
into industrial adamantine + 1u plasma dropper on metal extract) players
have no way to counter this as non living Golems are immune to damage.
This gives players counterplay, letting them disassemble Golem shells if
they can reach the factory, and scare off the creator.

## Changelog

balance: Golem shells can now be deconstructed with a crowbar (Not Golem
the species!)
