Volker Hilsheimer a8fee0bf43 Don't move focus away from previous proxy in QWidget::setFocusProxy
This amends 23b998fa45, and the commits
3e7463411e and
947883141d. This change restores the
pre-5.13.1 behavior of setFocusProxy to not move focus away from a
previously set focus proxy.

With the previous changes, focus would move away from a proxy when a
new proxy is set, if the old proxy had focus. While there are arguments
in favor of this behavior, it is a change of behavior that shouldn't
be introduced to 20+ years old functionality in order to fix the real
bugs addressed by the initial commits.

Instead, move focus only to the new proxy when the focus widget was
the widget that gets a focus proxy.

[ChangeLog][QtWidgets][QWidget] setFocusProxy no longer moves focus
away from a previously set focus proxy, restoring pre-Qt 5.13.1
behavior.

Fixes: QTBUG-83720
