Convert most of /obj/machinery to use Initialize rather than New (#17845)

* Switch a bunch of /obj/machinery from /New to /Initialize

This is an easy and uncontroversial batch.
No globs, no late init, and stuff.

* Move more machinery to Initialize

This time the ones dealing with GLOB vars,
as well as some simpler ones i missed previously.

* More tricky New -> Initialize migrations

* The last of machinery Initialize conversion

* fixups

* Newscaster armor fix

* styling

* Comment on armor handling

* Move newscaster armor definition back to datum
