<pre>selectItemsPos is implemented by VCLXListBox::selectItemsPos in
toolkit/source/awt/vclxwindows.cxx and that loops over each index and calls
ListBox::SelectEntryPos in a loop where SelectEntryPos is in
vcl/source/control/listbox.cxx where the slow bits seems to be the very
expensive CallEventListeners calls
checking VclEventId::ListboxSelect uses I don't think there is any use of the
position argument passed in so I don't think that matters too much, consumers
seem to just look up what is selected themselves, so its plausible that we
could get away with a single CallEventListener in this scenario
