Add parsing for between street lines

This CL adds type parsing for ADDRESS_HOME_BETWEEN_STREETS_1 and
ADDRESS_HOME_BETWEEN_STREETS_2. It is implemented behind the feature
flag kAutofillEnableSupportForBetweenStreets.

The field is classified as ADDRESS_HOME_BETWEEN_STREETS_2 only if
there exists a field with type ADDRESS_HOME_BETWEEN_STREETS_1.

With this CL, the regex for spanish locale for
ADDRESS_HOME_BETWEEN_STREETS is changed to search for "calles" instead
of "calle". As a side effect, single address between street fields with
name/label as "calle" would be labeled as ADDRESS_HOME_BETWEEN_STREETS_1
now instead of ADDRESS_HOME_BETWEEN_STREETS.
