QItemSelectionModel: refactoring of internal functions

Browse Source 
Introduce template helper function qSelectionIndexes().
Template argument is container. Now we have the same code for
QVector and QList.

Also it's needed for a follow-up change in this file:
add method QModelIndex QItemSelection::index().
