Added stub implementation of SharedWorkerRepository.

Turn on ENABLE_SHARED_WORKERS by default, but disable the SharedWorker bindings
so they are not available. This allows the SharedWorker code to get compiled in
to fight against bit rot, but prevents applications from using this API yet.

TEST=existing layout tests suffice
