Un-Hardcode water evaporation & mopping behavior (#33399)

* Un-harcode slipperiness

* Make it actually work

* Prettyfy

* Cleanup GetEvaporatingReagents

* Fix mopping with space lube + wrong solutions in absorbance

* Remove LINQ and rename parameters

* Change evaporation speed to fixedpoint2

* Add evaporating speed functionality

* Remove unused imports

* Swap around reagent evaporation speed and puddle evaporation speed.
