Port over improvements to lab tools

Summary

SUMMARY: Balance "Microcentrifuges can also separate, port over recipe for separation funnel"

Purpose of change

So a while back Critsybear remarked in his recent BN playthrough that it's really weird that you can't use the microcentrifuge to do separation work, when that's part of what it's for. Turns out after a quick search I found a PR that agreed with this sentiment, but it got canned under the apparent belief that you can't separate a suspension using another tool that's literally designed to do that kinda thing. Also evidently a tool that analyzes a blood sample as a plot point during a mission can't do analysis, lel.

However, my initial plan to port over that PR has to be shelved because it turns out terrain can't yet make use of crafting_pseudo_item. I'll need to save that for a follow-up PR, in which I either convert centrifuges to furniture, or figure out how to rig support for terrain providing crafting stuff.

Aside from realism, remaining changes make separator funnels less of a roadblock to mutagen production.

Describe the solution

1. Gave microcentrifuge the separation quality.
2. Ported over a recipe that makes separation funnels craftable. I decided to roll the needed plastic stuff into the recipe itself, instead of the source PR having a separate recipe for an otherwise-not-used-for-anything stopcock item. I would've had to hunt down whatever PR added said stopcock item anyway.

Describe alternatives you've considered

1. Simplifying mutagen production to not use a ton of science tools that have literally no other use in BN or DDA.
2. Adding more uses to said otherwise useless tools, this PR is already technically a step towards that.

Testing

1. Checked affected files for syntax and lint errors.
2. Load-tested in test build.

Additional credit to Critsybear for his BN playthrough as Numerius, and for reminding me about this in DMs (after which I kinda forgot, whoops).

Not covered by the above: addition of separation quality to microcentrifuge.

To be done in a follow-up: Centrifuge update PR, by zachary-kaelan: CleverRaven/Cataclysm-DDA#34344

Source provided in in Zach's PR that covers a good bit of details on the use of funnels vs tubes: https://chem.libretexts.org/Bookshelves/Organic_Chemistry/Organic_Chemistry_Lab_Techniques_(Nichols)/04%3A_Extraction/4.06%3A_Step-by-Step_Procedures_For_Extractions In particular, see the "Microscale Extractions" section, which covers the use of centrifuge tubes (either on their own or after running through a centrifuge).

Pinging @zachary-kaelan as they may enjoy seeing their work make it into BN. Leaving the mention here so they aren't potentially left wondering about a phantom ping, their idea will be ported to BN soon hopefully.

Huh. Terrain doesn't have support for crafting_pseudo_item? I could've sworn it did?

Requires full set of tools, but only cheap ingredients.
4 fab would be good.

Lel, more results of copying DDA's recipes. Will do.
