QQuickItem: correct focus reason for key navigation

Before we used Qt::OtherFocusReason for normal key navigation, such
as up/down/left/right. But in style world, the reason is critical
for focus change.

Now we follow the way in widgets world, use Qt::TabFocusReason and
Qt::BacktabFocusReason for down/up and right/left(or reversed if
mirrored).
