Subject: 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
