* ns/nim: Stub eShop related calls
As we aren't able to process purchase on the eShop throught the emulator, I have:
- Stub IPurchaseEventManager::SetDefaultDeliveryTarget (with RE check).
- Implement IPurchaseEventManager::GetPurchasedEventReadableHandle (with RE check).
As we can't do any eShop async call throught the emulator, I have:
- Stub IShopServiceAccessServerInterface::CreateServerInterface
- Stub IShopServiceAccessServer::CreateAccessorInterface
- Stub IShopServiceAccessor::IShopServiceAsync
Close#1084 and #1322
