Decouple CommandHandler.h/cpp from the BUILD.gn build rules of app/interaction-model (#33595)

* Initial version of splitting out command handler dependencies

* Restyle

* move privilege-storage based on dynamic server build rules...this is somewhat messy

* More dynamic server fixes

* Another gn fix for android/dynamic-server builds
