Remove QSignalMapper::mappedWidget()

mappedObject() can do exactly the same thing, there's no need for a
mappedWidget() signal as well

This removes a reverse dependency between Qt Widgets and Qt Core where
QWidget pointers are being used inside Qt Core.

[ChangeLog][QtCore] Removed QSignalMapper::mappedWidget. Connect to
mappedObject instead, and use qobject_cast<QWidget *> to handle Widgets.
