QQuickItemView: Fix max(X/Y)Extent()
QQuickFlickable maxXExtent() and maxYExtent() return the amount of space
that is not shown when inside a ScrollView. QQuickItemView however just
returned width() if vertical and height() if horizontal. In these cases
just defer to the QQuickFlickable base implementation like minXExtent()
and minYExtent() already do.
This change also adds tst_qquicklistview2 to speed up development.
tst_QQuickListView is almost 9000 lines long, and compiling it
is slow. In addition, a similar approach (creating a second test to
avoid the slowness of a massive one) already exists for QQuickItem
tests.
Fixes: QTBUG-83890
Pick-to: 5.15
