modules/atmospherics major cleanup (#61904)

major cleanup of modules/atmospherics folder and all related files, still many missing
-cleanup of procs name
-cleanup of vars name
-documentation of some of the procs
-minor changes to some for() logic (no in game changes just early continue or as anything checks)

No in game changes, only code and docs
