bind-gen: Enable the new IDL dictionary implementations

Enables the new IDL dictionary implementations.

The APIs are compatible and no major difference, but there are
minor differences between the old and new IDL dictionary
implementations:
1. Exact distinction between "missing" and IDL null.
(dict->foo() is invalid when !dict->hasFoo().)
2. Use the new IDL unions and the new IDL enumerations as
member types of the IDL dictionaries.
3. Move support for (Heap)Vector members.

The pinpoint result:
https://pinpoint-dot-chromeperf.appspot.com/job/1484ae38320000

bind-gen: switch
