Drastic Lag Mitigation Subsystem: SSlag_switch (#59717)

Browse Source 
Requested by oranges and inspired by the upcoming event. A new subsyetem, non-processing (for now), aimed at providing some toggle switches that can be flipped as a last ditch effort to save some CPU cycles by sacrificing some non-critical mechanics. Below you can see each individual toggle.

Screenshot of the admin panel:

Surely there are more opportunities for toggles I missed, but adding new ones is not very difficult at all.
Why It's Good For The Game

Better performance during extreme pop, I hope.
Changelog

cl
code: Introduces the Lag Switch subsystem for when a smoother experience is worth trading a few bells and whistles for. Performance enhancement measures can be togged by admins with the Show Lag Switches admin verb or enabled automatically at a pop amount set via config.
config: Added a new config var: number/auto_lag_switch_pop
