Change power efficiency numbers

Summary

SUMMARY: Balance "Change power draw of vehicle parts and electric tools to reflect reality"

Purpose of change

A lot of power draw numbers were a long way off from reality and/or hadn't been updated when everything switched to watts. With the recent and future changes increasing energy scarcity incredibly inefficient devices would become an obvious problem. Imminent changes to make turn and action lengths more realistic will also make such inefficient hardware look more like 0A era kind of artistic license physics.

Describe the solution

Change values for electric power draw to accurately reflect reality. In most cases this has meant significantly increasing energy efficiency.

Additional context

The vehicle epower changes should be fine now but changes to turns_per_charge values shouldn't be merged until after #30253 or electric tools will be six times more efficient than they should be.

Please update the docs so future contributors know how to convert watts to turns_per_charge.

Also consider replacing turn_per_charge with "watts" as a float in JSON and then converting it in the code. That would improve readability and make it much easier to convert to 1 second turns in the future.

Are you planning to adjust battery capacity in a similar fashion? Right now they use round numbers that don't make a whole lot of sense, and altering efficiency means that altering battery capacity might also be called for.

[Inglonias]

This is a ludicrous increase in efficiency. I wonder if we'll see any bug reports about tools suddenly having infinite battery life?

Added a new power_draw field and updated most items to use it. We should consider using mJ internally for storing energy as we have mW range items. Working accurately with integer kJ values is hard with low power over short times. We might also want a power string parser at some point.
