DO NOT MERGE Merge state producer and feature producer.

Browse Source 
Merge device state producer and display feature producer so that
FoldingFeature data has a single data pipeline. This should make it
easier to retrigger reading data if other signals are necessary.

Bug: 205342008
Test: manual - run sample app.
