Cuts down on unnecessary non-TGUI stuff (#79590)

## About The Pull Request

Removes INTERACT_MACHINE_SET_MACHINE on machines that don't use a
non-TGUI UI.
Removes set_machine from TGUI things that forgot to remove them
previously.
Decouples advanced camera consoles from UI procs since it doesn't
actually use one.

## Why It's Good For The Game

TGUI machines don't need to be using these procs and vars, and this
makes it more clear what does and doesn't use a TGUI menu from a glance.
I explain it a bit better
