[MIRROR] MODLink System (+ NWTLMM) [MDB IGNORE] (#23199)

* MODLink System (+ NWTLMM) (#77639)

## About The Pull Request
A pact made with `@ Kapu1178`
Small changes you should not care about:
RD MODsuit outfit (admin only) no longer has a beret that blocks the
activation of the suit
The beret used by death squad officers no longer is blocked from being
put on a hat stabilizer module
Admins can now Shear matrices of objects in Modify Transform
Multitool buffers have been a little refactored to use a setter proc
that saves them from causing hard dels
Cooler stuff:
A revival and remake of [Nobody Wants To Learn Matrix
Math](https://github.com/tgstation/tgstation/pull/59103), this time with
additional tooling for quick matrix calculations.

## Why It's Good For The Game
Adds a fun way for the crew to communicate with each other that can be
done in real-time with relative privacy compared to radio.
