QQuickTableView: add a new 'alternatingRows' property

Add a new property 'alternatingRows' that informs the
delegate that it should alternate between rows.
This is merely a hint, the delegate is free
to ignore it. But our own internal delegates, like
TreeViewDelegate, should not.

[ChangeLog][Quick][TableView] Added a new property
'alternatingRows', which is a hint to the delegate
to alternate between rows.
