Implement setDoubleStep for QInputDialog
setDoubleStep works in the same manner as for setIntStep in that it is
just available for input dialogs getting a double.
[ChangeLog][QtWidgets][QInputDialog] Added setDoubleStep to enable
changing of the step amount for getDouble().
Task-number: QTBUG-17547
