[Maps] Add back removed logic copying feature properties for injected…

… data (#49400) (#49698)

* Add back removed logic copying feature properties for injected data prior to modification

* Back out injected data and assign featureCollection to sourceDescriptor with __ prefix

* Review feedback. Ensure __featureCollection is always initialized minimally to a geojson object with an empty features array

* Check for null/undefined
