1984 "Unobtainium Chemistry" (#1600)

# Description

Making chems use Unobtainium Reagents doesn't make chemistry
interesting, it makes medical gameplay boring. This PR replaces the
unobtainium recipes with suitably expensive and/or complicated recipes.
Have fun memorizing how to make Acetone, Ammonia and Impedrezine.

# Changelog

:cl:
- remove: 1984'd most instances of "Unobtainium" chemistry. Chems like
Necrosol that previously required normally unobtainable reagents such as
Cognizine or Vestine now instead have long production chains of chems
that are obtainable, but complicated to produce. Check the chemistry
menu for more information.
