Update CTS tests for res.Configuration adding locale lists.

This especially focuses on cases where the deprecated 'locale'
attribute is used together with setLocales().

Also:
* Add CTS tests for new LocaleList methods introduced for
  res.Configuration needs.
* Remove the perhaps overreaching requirement that the system's
  default locale should be be LTR.
* Correct the country code for the Persian locale.
* Add a locale for Urdu to layout direction tests.
