Better DNA forensics & ReagentData (#26699)

* Added the ability for blood to track DNA using ReagentData; Forensic Scanner now accounts for solution DNA, non-DNA holders have "Unknown DNA"

* Removes touch DNA for puddles, adds DNA to vomit

* DNA now leaves traces in containers and those marked without don't show DNA on scan (except for puddles), gibbed parts have DNA

* Fix stupid metamorphic glass bug grrr

* Removed SpillableComponent since DnaSubstanceTraceComponent is used instead

* Removes data field from maps, adds DNA tracking for some missed items

* Give default value, fix missing values.

* Fixes recipe bug

* Review changes

* Make the Data list into a nullable type

* Revert map changes

* Move gibbed unknown DNA to forensicssystem
