reduce lathe recipe copy pasta (#31515)

* add inheritance to lathe recipes and make result an override

* add GetResult method to lathe system

* make other parts of the code use GetResult

* clean up the stock parts yml

* remove unused apu boards from dynamic recipes

* make inverse dictionary public so test doesnt have to copy paste

* revert result override stuff
