Faster, non-blocking world init (#23136)

* Moves turf New calls to Initialize

* Much faster

* Fixed

* Makes add_to_active queue up before SSair is initialized

* Remove active queuing

* And the proc

* Move the check

* Fix some shit

* F U C K T U R F S

* Necessary

* Unnecessary

* SHUT THE FUCK UP

* Panic mode hurts the code

* Such a

* Simple answer

* A well thought out plan

* /turf/open optimization

* Undo the warning suppression now that it's fixed

* Fixes lava typecaching badly

* Added late initialization

* Make the atmos offenders late initialize

* Add extra logging

* GLABALS

* Better solution for trying to activate w/o air

* Further base calling copypasta

* Gates, guards, gorans

* Small doc fix

* Do the faster

* T U R F   V A R   P E R S I S T E N C E

* The solution is always so simple

* The (hopefully) final nail in the coffin
