Settings: Meet BYOD check intent filter expectations.

  CTS Verifier expects SecuritySettings to contain Lockscreen options, thus
  if SecuritySettings are externally invoked and disambiguated by intent
  resolution, we need to display both lockscreen options and security options.

  AOSP provides an activity that handles android.settings.BATTERY_SAVER_SETTINGS
  thus, we provide an activity-alias that points to the PowerUsage menu
  to meet the expectation of the cts verifier request.
