LateInitialize is not allowed to call parent anymore (#82540)

## About The Pull Request

I've seen a few cases in the past where LateInitialize is done cause of
the init return value being set to do so for no real reason, I thought I
should try to avoid that by ensuring LateInitialize isn't ever called
without overriding.

This fixes a ton of machine's LateInitialize not calling parent
(mechpad, door buttons, message monitor, a lot of tram machines,
abductor console, holodeck computer & disposal bin), avoiding having to
set itself up to be connected to power. If they were intended to not
connect to power, they should be using ``NO_POWER_USE`` instead.

Also removes a ton of returns to LateInit when it's already getting it
from parent regardless (many cases of that in machine code).

## Why It's Good For The Game

I think this is better for coding standard reasons as well as just
making sure we're not calling this proc on things that does absolutely
nothing with them. A machine not using power can be seen evidently not
using power with ``NO_POWER_USE``, not so much if it's LateInitialize
not calling parent.

fix: Mech pads, door buttons, message monitors, tram machines, abductor
consoles & holodeck computers now use power.
