More Fields for Autofill Profile Validation API

-- The autofill profile validation API can now validate
   locality (like city or ..) and dependent locality 
   (like neighborhood, district or ..) fields.

-- If a field is required, it should not be left empty.
An empty required field is considered as invalid.

-- If a field is filled, 
and the rules for validating that field are available in the source,
then the field will be validated according to the rules.

-- Even if a field is not required, but it's filled and it is not
valid according to the rules in the source, the field would be marked
as invalid.

-- Unit-tests added for new fields.

-- Unit-tests added for a country with a non-Western language.
