Mark ApiQueryBase methods accepting arrays

These particular functions build up data to be passed into the database
abstraction, which accepts not only strings but arrays. Where conditions
generate `field IN ('a', 'b', 'c')` clauses. The options can be used
with, for example, sort to sort by one field and then a second.
