[MIRROR] Buildable mass drivers [MDB IGNORE] (#23776)

* Buildable mass drivers (#78360)

## About The Pull Request
Adds the ability to build mass drivers, you activate them by attaching a
signaler to their launch wire. They also have a safety wire, that when
pulsed, increases the power of it. To reset the power back to normal you
cut the safety wire. This is mostly just a port of
https://github.com/BeeStation/BeeStation-Hornet/pull/5563

## Why It's Good For The Game

Less weird unique machines, and you can do some interesting stuff with
mass drivers, like traps, cannons, and many other interesting things.

## Changelog

🆑
add: mass drivers are now buildable, you activate them by attaching a
signaler to their launch wire, and can increase their power by pulsing
the safeties wire, and reset it back to normal by cutting the safeties
wire.
