Standardize cleaning object behavior into "cleaning_act" proc (#19001)

* Standardizes cleaning item functionality into "cleaning_act" proc

* Culling commented-out code

* Damp rag now checks for humans before cleaning

* Change proc scoping, moved mop reagent check out of cleaning.dm

* Adds can_clean and post_clean procs to handle mopping, removes ismop parameter

* Adds can_clean() to cleaning objects/mobs

* cleaning_act() now carries message strings as params

* Refactored cleaning_act() for earlier returns and less redundancy

* cleaning_act now runs on the target atom, instead of the cleaning object

* Changed turf checks to overrides, rescoped clean_turf, lots of tidying

* Removed cleaner param from post_clean, since it'll always be src

* Code review tidying

* Tidying..........

* Removed clean_turf and put its functionality in turf/simulated/cleaning_act(), added new param to keep track of original targeted object

* Moved cleaning.dm from datums to code/game/objects

* Added early return, defined cleanspeed in seconds
