          DisplaySettings: Add hardware-framework support for tap-to-wake

          Since we have tap-to-sleep globally, might as well support the
          wake gesture as a standalone thing through the HAF. Place it in
          "Display".

          Settings: set proper default value for tap to wake

          The first time the display_settings.xml file gets inflated, the
          PreferenceManager takes the defaultValue and persists it in the default
          shared preferences file.
          When we read the double tap to wake preference,
          we assume it has a default value of true, which it uses until the user
          enters Display Settings for the first time. At that point, the default
          value is persisted, and every boot after will use the default value in
          display_settings.xml.
          Remove the default defined in the XML file.
