[MIRROR] Medipens can't have reagents removed from them anymore. (#1833)

* Medipens can't have reagents removed from them anymore. (#82451)

## About The Pull Request

This will be needed for
tgstation/tgstation#82449 because this removes
the machine's ability to make infinite chems.
Basically in tgstation/tgstation#29139 they
removed medipen's ability to have reagents injected into them, but never
removed the ability to take reagents out.
You could take a syringe, remove all chemicals from a medipen, put the
main ingredient in a medipen refiller, then refill. You could do this
right now on live servers with an epipen for infinite formaldehyde.

This doesn't affect the hypospray.

## Why It's Good For The Game

Removes a way of infinitely making reagents with a medipen refiller and
also removes a dumb mechanic.
You could take all chemicals out of an EHMS autoinjector, which removes
the visual and feedback tell to the target that they've been injected,
and even with 0 chemicals they get the disease anyways.
You could buy medipens as a miner, take the chemicals out, and put them
in a syringe or pill that you can inject yourself instantly with.
You can take otherwise hard-to-get chemicals like fungal TB's 2-use cure
injector, and make 40 cure pills instead.

## Changelog

:cl:
fix: You can no longer take chemicals out of medipens with a syringe.

* Medipens can't have reagents removed from them anymore.
