Support array types for function and callback arguments in IDL APIs.

I realized we completely omitted array support with our initial IDl work. This
patch fixes that for 2 important cases, but doesn't yet add it in for 
dictionary members (that can be a separate patch).

BUG=122875
TEST=Included unit tests should pass
