Replaces our lighting system with CM's. (#21465)

Depends on #21458.

Ports https://github.com/cmss13-devs/cmss13/pull/4229, with the original
authors as:

- https://github.com/tgstation/TerraGov-Marine-Corps/pull/1964 for the
lighting controller (A-lexa)
- https://github.com/tgstation/TerraGov-Marine-Corps/pull/4747 and
https://github.com/tgstation/TerraGov-Marine-Corps/pull/7263 for the
lighting (TiviPlus)
- https://github.com/tgstation/tgstation/pull/54520 for the dir lighting
component
- https://github.com/tgstation/tgstation/pull/75018 for the out of
bounds fix in lighting
- https://github.com/tgstation/TerraGov-Marine-Corps/pull/6678 for the
emissives (TiviPlus)

The main driving reason behind this is that current lighting consumes
way too much processing power, especially for things like odysseys/away
sites where a billion light sources are processing/moving at once and
the game slows down to a crawl. Hopefully this improves the situation by
a good margin, but we will need some testmerging to confirm that.
