[MIRROR] Integrated circuits for modular computers (#26196)

Integrated circuits for modular computers (#80530)

This PR integrates circuits for modular computers and a good bits of
their programs.
The peculiarity here is that modular computers have no fixed amount of
unremovable components (except the base one with just a couple ports for
now), instead, they're added and removed along with programs. With a few
exceptions (such as the messenger and signaler), for these program
circuits to work, their associated program has to be either open or in
the background.

For a reason or another, not all programs have a circuit associated to
them, still, however the programs with a circuit are still a handful.
They are:
- Nanotrasen Pay System
- Notepad
- SiliConnect
- WireCarp
- MODsuit Control
- Spectre Meter
- Direct Messenger*
- LifeConnect
- Custodial Locator
- Fission360
- Camera
- Status Display
- SignalCommander

*By the by, sending messages has a cooldown, so it shouldn't be as
spammy. If it turns out to not be enough, I can make it so messages from
circuit will be ignored by other messenger circuits.

The PR is no longer WIP.

I believe modular computers could make for some interesting setups with
circuits, since they're fairly flexible and stocked with features unlike
many other appliances, therefore also a speck more abusable, though
limits, cooldowns, logging and sanitization have been implemented to
keep it in check.

🆑
add: Modular Computers now support integrated circuits. What can be done
with them depends on the programs installed and whether they're running
(open or background).
add: Modular Consoles (the machinery) now have a small backup cell they
draw power from if the power goes out.
