ListView: order section headers before their items in the focus chain

Tab/backtab navigation between sibling items follows the contentItem's
child-stacking order (see QQuickItemPrivate::nextTabChildItem()), not
their visual geometry. Section headers and delegate items are parented
to the contentItem in creation order, which need not match the visual
order: a section header is created after the delegate item it precedes,
and items added while flicking backwards are appended to the child list.

Re-stack the visible delegate items and their section headers whenever
the visible set or the section assignments change, so that the focus
chain follows the visual (top-to-bottom) order, with each section header
immediately before its delegate item (e.g. section A, then items A1, A2,
A3). stackAfter() is a no-op when an item is already in place, so this is
inexpensive for a stable view. Only items in visibleItems are touched;
the header, footer, highlight and sticky section items are left
untouched, and z values are unchanged so the visual stacking order is
unaffected.
