Subject: [PATCH] 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.
Fixes: QTBUG-83890
Pick-to: 6.2 6.4
Change-Id: I7f4060c2f46ae07611bedceca0d322c5f7f6affb
