Shell May Cry: A comprehensive rework of synthetics. (#20721)

https://www.youtube.com/watch?v=9mPvZ96pHJI

A pull request commissioned by the Synthetic Lore Team to
comprehensively rework synthetics (read: IPCs) and how they work in
Aurora. The objective is to make IPCs as unique as possible from humans,
upgrading the robotic feel and atmosphere, while also preserving a good
sense of balance in-game.

Key features:

- A comprehensive expansion of synthetic organs, all of which now
fulfill a purpose: hydraulics, cooling units, power systems, actuators,
diagnostics units.
- Customizable organs with benefits and drawbacks, such as with cooling
units and power systems.
- Unique ways to repair the organs and more involved steps.
- Unique damage mechanics - every organ has wiring and electronics which
affect its functioning, and they are defended by plating which provides
natural armour.
- Improved and immersive diagnostics.
- Unique features, benefits, and drawbacks for every IPC frame.
- A rework of the positronic brain, which can be either destroyed or
shut down, alongside effects caused by low integrity.
- A rework of how EMPs affect IPC organs.
- Non-binary damage states for each organ.

To-do:

- [x] Finish the unique features for each frame.
- [x] Look into if mechanical synthskin is possible.
- [x] Power system.
- [x] Posibrain mechanics.
- [ ] Passive cooling expansion.
- [x] EMP mechanics.
- [x] Repair mechanics.
- [x] Mob weight mechanics.
- [ ] Gurney for heavy mobs.
- [x] New augments.
- [ ] IPC tag scanning and flashing.
