Adds tongs (tgstation#78698)

## About The Pull Request


![dreamseeker_6nkq7xbypa](https://github.com/tgstation/tgstation/assets/7483112/60f86b9d-a5aa-4630-8ab4-8956b2e44665).

Adds tongs, as requested on the [Official TGStation13
Forums](https://tgstation13.org/phpBB/viewtopic.php?f=9&t=33026)
Tongs can be used to pick up food from two tiles away, and feed it to
people who are two tiles away.
You can also use them while in your hand to snap them together like a
crab, or use them to harmlessly pinch people who are up to two tiles
away.

Tongs are available from the kitchen's dinnerware vendor, the autolathe,
and the service lathe.

## Why It's Good For The Game

You can feed people from across a counter, without touching the food and
spreading your germs to them.

## Changelog

:cl: Coded by Jacquerel, Sprited by Dalmationer
add: Added tongs to the kitchen, which you can use to manipulate food
from further away
