[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.

The MODLink system, available through every MODsuit and MODLink scryers
(a neck item obtainable from advanced modsuit research or
charliestation)
Let's you make a holographic call with any other MODLink user, where you
can chat in realtime and see what's up with em

## 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.
