Generalizes the chemical blacklist, refactors some other chemical lists and cleans up some related code (#21810)

* almost done

* HELP, SCOPE KEEPS INCREASING

* if this isn't the last thing, blame my sleepy me

* fucking foam all my homies hate foam

* remove the extra whitespace

* ghhh this needs testing + revert old shit

* first sleeper steps

* okay now to revert some changes

* oops forgot this

* more fixes

* iv bags can't dupe shit anymore too

* removes coniine from the list because why not

* removes life and histamine

* this should pass Cl

* stop runtiming me for unexisting chemicals

* adds ???? instead + god I hope this passes Cl

* attempt #2 to fix Cl

* Cl still fails but no solution now - static lists

* One fucking day Cl will not fail + complete remove

* I am going insane

* I am praying to several gods

* I'm getting desparate

* whoops that's my bad

* whoopsie number 2

* oops space indentation

* one rubber ducky later

* attempt number I am in a psych ward

* CODING CHAT MY BELOVED

* last things

* foam is also not a chemical

* now it shouldn't remake the list every time

* Henri review

* Adds saturated activated charcoal

* Charlie review
