IDBAny need not be scriptwrappable.

V8IDBAnyCustom.cpp will call into toV8() for the appropriate type, which will in turn invoke wrap() for the appropriate type, which will perform the bindings integrity check.  Since IDBAny doesn't have its own wrap() method, there's no place that the check would actually be applied.  The presence of the IDBAny.idl was what triggered the conversion to scriptwrappable in the first place.

This does no harm, but wastes a few bytes of memory.
