Fixes self-sustaining rainbow slime extracts, blue slime extracts' foam activation and refactors foam code into a helper proc (#46259)

* Fixing self sustaining rainbow extracts and fixing foam creation of blue slime extracts

* Refactoring foams to be in a helper function. Resin foam remains untouched

* Improving refactor of create_foam

* Putting helper proc in vent clog event

* create_foam takes a foam type again

* minor type passing change
