Summary Remove implicit "= {}" and "= []" default values for IDL optionals

We currently ignore the "{}" default value (parsing it and then pretending it didn't exists) and instead treat all optional dictionaries as if they had it, confusingly using "[]" to track that. We should do this the right way.
