Turn ReagentEffects into generic EntityEffects (#28168)

* Oh the possibilities

* Merge fixes

* Forgot to remote LavaSystem oops

* Changed EntityEffectArgs to EntityEffectBaseArgs and EntityEffectReagentArgs

* Throw exception for unimplemented effectargs

* Remove Json and overrideable datafields

* Fix test issues

* Actually fix the compiling issue

* Fix comments and remove EntityEffectArgs (no longer used, replaced with EntityEffectBaseArgs)
