* From tgstation/tgstation#27196
* The mc will now punish subsystems that overrun their tick allotment with less allotment in later fires.
* The punisher also delays the next fire of subsystems that overrun. Because of how this is ends up being calculated, this will almost never actually kick in, but sometimes subsystems like garbage will overrun into multiple ticks, so delaying their next fire is needed.
* The punisher does not delay the next fire of SS_TICKER subsystems (tgstation/tgstation#34964)
Note: SS_KEEP_TIMING subsystems do not get their next fire delayed.
* This is PHASE 1 of a multi-phase conversion. In this first phase we implement the subsystem, but leave it processing the existing global list variables. In the next phase we will switch to use datum variables in the subsystem. The main reason for splitting into two phases is ease of code review; change the meaningful code without the hundreds of machines -> SSmachines.machinery substitutions.
* We did declare macros for adding/removing things to the processing lists, and convert everywhere to use the macros.
* Added var/is_processing to /datum to keep track of whether an instance is already in a processing list (prevents it being in the list twice!) and also debugging, making sure its not in two lists etc.
* NOTE: The global machines list is **no longer sorted** for performance reasons. As far as I know, the only module that actually ever cared was cameras. Our camera system already handles its own sorting in the cameranets anyway, so it should no longer be needed.
* Adds defines for world.tick_usage
* This provides no useful benefit whatsoever, but /tg and Baystation12 have done it, so it will make porting future code easier if we do too. No real harm done either.
* Based on https://github.com/tgstation/tgstation/pull/25386
* Create macro for defining new subsystem types.
* Create PreInit proc to handle setup that needs to be done before the map loads
* Rename garbage_controller subsystem to garbage so it matches its global SSgarbage variable name.
