Fixes complex lights not handling moving well, renames lighting defines (#81423)

## About The Pull Request

[Fixes static lights not
moving](https://github.com/tgstation/tgstation/commit/ffef43c05a55dae414ef94558ecf9b9df709ded7)

Worked fine when the owner moved, but if the owner was inside something
else, it would try and trigger an update on the PARENT's lights, which
are obviously not us.

[Renames MOVABLE_LIGHT and STATIC_LIGHT to better describe what they
do](https://github.com/tgstation/tgstation/commit/de73a63bd4d97783c69c95370726d1c253ffb8fe)

People keep trying to change the lighting system of lamps and it makes
me mad.
I choose OVERLAY_LIGHT and COMPLEX_LIGHT here, I couldn't figure out a
better name for turf matrix lighting. Suggestions welcome

## Why It's Good For The Game

Closes #80005
Hopefully improves understanding of lighting at a glance
