Fix dictionary constructors to accept supertype members and create an empty object when there are no fields (#197)

Dictionaries can contain their supertypes' members as well and therefore, these constructors should accept them.

https://webidl.spec.whatwg.org/#idl-dictionaries
#188

We also emit some empty dictionary constructors, but because they are empty, they are treated as named constructors instead of object literal constructors. They should instead call JSObject() to create an empty object.

Since some supertype fields are marked required, this is technically a breaking change as calling the same dictionary constructor requires those members now. Therefore, bump to 0.6.0-wip.

+- Added supertypes' fields to dictionary constructors as dictionaries are

+- Empty dictionary constructors now create an empty object instead of being

 ## 0.5.1
 
 - Add [`TrustedTypes`](https://web.dev/trusted-types) members.
