Implement virtual void QPlatformWindow::setBackingStore()
QWidget re-uses an existing backing store. Platform windows depend on
being associated to a backing store, in case they become toplevel
windows. If a platform window gets deleted and re-created each time it
is shown or hidden, it has to be manually associated to the re-used
backing store.
This patch partly reverts fbf0aeea7d3b38ced7a16fcd5c3e2e9b45536292.
It removes Android specific code from QWidgetPrivate::create(), which
has been added to suppress re-using backing stores in the absence of
the new API.
Fixes: QTBUG-97482
Pick-to: 6.6
