Make use of multi-threading in KItemListSizeHintResolver.

We need the item size hints of all items in KItemListLayouter::doLayout(),
so instead of resolving it sequentially during layout calculation, 
we can resolve all item size hints in parallel before we start the 
layout calculation.
Everything works fine.

It is about 1/3 faster on my machine (tested with 100k items in item view mode).
