bindings: Use IDL dictionary to implement FontFaceSetLoadEventInit

This CL also adds an empty array default value ("[]") in IDL dictionary
as FontFaceSetLoadEventInit requires it.

PTAL?

Since FontFaceSetLoadEvent is [NoInterfaceObject] we don't have any layout tests
for the constructor. Per the spec, it should be exposed, but I guess that we
need to send an intent-to-ship before exposing FontFaceSetLoadEvent. Exposing
the event isn't the purpose of this CL so I didn't remove [NoInterfaceObject].
