Convert xml based API allowDynamicSummaryInSlice to java

- Add boolean useDynamicSliceSummary() in Sliceable interface. This is
  the switch equivalent to android:allowDynamicSummaryInSlice in xml. It
  moves the setter closer to regular Sliceable APIs, thus less easily to
  miss.
- Coverted all android:allowDynamicSummaryInSlice to use the java API.
  - Except 2 prefs in my_device_info. They incorrectly set this to true
  previously (controller is not sliceable, no point setting
  dynamicSliceSummary to true. They just won't do anything)
