Standardize MC subsystem initialization boilerplate

Browse Source 
* 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.
