Basic drones (#79109)

## About The Pull Request

Fixes #68825
Fixes #72249
Fixes #70184

Converts maintenance drones to use the basic mob framework. As drones
don't use AI, this was mostly a perfunctory conversion, but I took the
opportunity to clean up drone code a bit and fixed a few bugs.

Noteworthy changes:
- Drones now have a `can_unhack` field. This is set to FALSE on
syndrones, because unhacking them doesn't make them stop being evil but
does cause some weirdness. Syndrones are unused right now, but you never
know.
- Drones use the Dextrous component for hand-having.
- Drones no longer have an internal ID card, instead being given
all-access with the `simple_access` component.
- Picking up drones now works the same as for other mobs, instead of
pointlessly copying the code into `attack_hand`. As a consequence, it is
now possible to punch drones if you want to for some reason.
- Drones can now reboot/cannibalize dead drones without being in combat
mode.
- Cannibalizing a drone that contains a client no longer runtimes - the
client is ghosted ahead of time.
- Drones now have TRAIT_ADVANCEDTOOLUSER, allowing them to properly
interact with machines.
- Trying to screwdriver a dead drone now gives a balloon alert about why
you can't do that.

In addition to these changes, I cleaned up the code quite a bit,
organizing things better and placing more useful comments throughout.
And removing a hell of a lot of single-letter variable names.

I will note that this PR does _not_ address #72129. The issue there is
that sprites for drones-as-hats are entirely nonexistent, and I'm not a
spriter. It shouldn't be too hard to fix if someone makes dronehat
sprites, though!

## Why It's Good For The Game
Kills 8 more simple animals.

In addition to that, drones were clearly a bit neglected, so this fixes
them up a bit and makes the code a little bit clearer. Maybe not that
much clearer, but it's something. It certainly leaves them in a better
place for further work if anyone wants to do that. Plus, a bunch of bugs
and other jankiness are fixed now, which is nice.
