Update TARE UI.

1. Connect the UI and controller components so that users can make
   changes and the changes will be written to settings and properly read
   back.
2. Update string constants to reflect changes from TIP1.
3. Refactor components slightly to reduce duplicate code.
4. Hide unsupported factors for now. They'll be added back later.

Bug: 158300259
Test: Manually change factors and check settings constant via adb
