[runtime product] API cleanup: remove ProductMode.NOVA value (IJPL-797)

ProductMode class is in platform code, it isn't supposed to contain things related to specific products. Also, this new field isn't returned from ProductLoadingStrategy as the other. It was used in StatisticsEventLogger only, and that usage is now inlined.
