QApplicationPrivate::focus_widget became a dangling pointer
in the following scenario:
A widget first gets focus and later on gets a focus proxy.
QApplicationPrivate::focus_widget was still pointing to the initial widget.
Upon destruction, QWidget::hasFocus() [which follows to the focus proxy
and then compares with focus_widget] was therefore false for both
widgets. So QWidget::clearFocus() didn't call
QApplicationPrivate::setFocusWidget(0) for either of them. As a
result, focus_widget remained set, and became dangling.
In real life, this happened with a QWebEngineView, which the application
gave focus to upon creation. At that time it doesn't have a focus proxy
yet. That happens later, in QWebEngineViewPrivate::widgetChanged.

The public QWidget::create still has them, but we don't need to
propagate them on - that just makes debugging the window creation
flow harder.
The window argument to QWidget::create is technically used to
guard an early exit in the function, but to keep behavior the
same we leave it for now.

QWidgetPrivate::updateIsTranslucent sets the surface format of the
window with the alpha based on the translucency attribute, so we need
to call this function when the attribute value changes. The test can
confirm that the window's requested surface format has changed, we
can't rely on what is actually set, and don't have to rely on
hard-coded values like 8bit alpha.
While WA_NoSystemBackground needs to be set for WA_TranslucentBackground
to have an effect, we can't clear the attribute when clearing
translucency (as it might have been set explicitly).

The completer popup has focus, making QShortcut direct to it's window
rather than to the window the completer belongs to. As QShortcut handles
the case for Tool windows that have a parent, but doens't do the same
for popups. And they shouldn't be treated the same way, as a context
menu popup for a e.g. text edit should in fact block the text edit's
shortcuts while open.
However, the completer popup is special, in that it explicitly makes the
widget completes for its focusProxy, which is what we can use to fix
this issue.

81e298a51d fixed a case where the focus
chain was screwed up when the order was already correct. This worked
correctly in most cases but not when the next focus widget of the first
one had Qt::NoFocus.
The optimization check if lastFocusChildOfFirst is the same as second is
thrown away since it now does not longer screw up the focus chain and
the save would only be four pointer assignments.

In some cases, a tool tip may be shown outside screen geometry, i.e. if:
- QToolTip::showText is invoked manually with a position outside.
- In tst_QToolTip::setPalette if there is no screen at (0, 0). This might
happen in a multi-monitor setups where one screen is taller than the other.
- On Wayland windows are (by design) not allowed to know their position on
the screen. This means that global positions can't be trusted.
This started crashing when QDesktopWidget::screenGeometry(pos) was replaced
with QGuiApplication::screenAt(pos)->geometry() because screenAt will return
null if no screen is found, while screenGeometry defaulted to the primary
screen.
This reverts to the old behavior of falling back to the primary screen.
This won't solve the issue completely for the Wayland case, but at least we
will stop crashing.
