Adding sound/haptic settings.

Add Wear haptic settings for Active Unlock in main. These changes exist
only in tm-wear-kr3 right now, which means they need to be migrated to
main, and then later cherrypicked down. These global settings will be
accessible by other areas and are part of adding toggles to the Settings
pages on the watch.
