[JPS] Rebuild module on facet change

The logic of detecting changes in Kotlin facets was changed from "Include selected fields" to "Include all compiler arguments and exclude selected". This will help to avoid multiple IC issues when new change-sensitive compiler arguments will be added

(#KTIJ-17137, #KT-51536, #KTIJ-17170, #KTIJ-17300, #KT-47983) Fixed
