Replaces a bunch of obj vars (and emagged on machinery/items) with obj_flags (#34078)

* It works, but is it worth it?

* bitfield helpers take 1

* Would this work?

* remove dangling debug code

* rebase & fixes

* vv bitfield stuff, reading

* DNM oceans of shitcode DNM

* honk

* honk2

* plonk

* rebase & fix
