[Ready for review/merge]Rolls chainsaw surgery into prosthetic replacement, makes synthetic armblades implantable (#23213)

🆑 XDTM
tweak: Implanting chainsaws is now a prosthetic replacement instead of its own surgery.
add: You can now implant synthetic armblades (from an emagged limb grower) into people's arms to use it at its full potential.
del: Chainsaw removal surgery has been removed as well; you'll have to sever the limb and get a new one.
/🆑
Reason for adding

Makes the surgery code more consistent, without a snowflake surgery for chainsaws. This also gives a legitimate use for synthetic armblades, which were otherwise just a much shittier and harder to get circular saw.
