Add commands queue to iOS EventsDispatcher

[Alex009]

To support case of immediate dispatches after EventsDispatcher pass to ViewModel:

class EnterPhoneScreen(
) : WidgetScreen<Args.Empty>() {
    override fun createContentWidget(): Widget<WidgetSize.Const<SizeSpec.AsParent, SizeSpec.AsParent>> {
        val viewModel = getViewModel {
            createViewModel(createEventsDispatcher()).apply { start() } // HERE RUN START, where event call immediate
        }
        viewModel.eventsDispatcher.listen(this, this) // HERE SUBSCRIPTION

        // ...
    }
}
