Cybernetic arm implants now automatically change insertion zones (#89479)

## About The Pull Request

Removes weird requirement to screwdriver arm implants to change them
into a specific configuration. Instead, they now automatically slot into
whichever zone the user has selected.

## Why It's Good For The Game

Its kinda unintuitive and a result of organs only being able to slot
into a single zone. I'm not generalizing this to organ layer because arm
implants are the only thing that does this, but if we ever get leg
enhancements it may be worth moving down into the base class.

## Changelog
🆑
qol: Cybernetic arm implants now automatically change insertion zones
without the need to screwdriver them.
