Fix endless loop on race condition on qemu startup
Fix wierd race condtion which ends in endless loop with
single-process, when gpu_channel_host is not ready in
WidgetBase::RequestNewLayerTreeFrameSink and calls
callbeck with nullptr, which ends in
LayerTreeView::DidFailToInitializeLayerTreeFrameSink
which again calls RequestNewLayerTreeFrameSink wihout giving
a chance to initalize channel and round repets itself.
Give 10ms delay to cover the issue.
Task-number: QTBUG-105342
