Summary Distinguish between Callback and Dict in IDL

Currently the IDL generator does not correctly generate code that distinguished between Callbacks & Dicts. Creating an IDL like `dictionary Foo {}; type (VoidCallback or Foo) MyUnion;` results in roughly `std::variant<VoidCallback, Foo>` but it will always hit the `Foo` variant when visited. https://github.com/whatwg/webidl/pull/1353 has been merged so this should be rectified.
