Rendering a widget to a paintdevice via QWidget::render() did not pass
the LayoutDirection mode of the widget to the paintdevice which lead to
wrong rendering of text.

When a QWidget was reparented, we would take care to reparent its
backing QWidgetWindow as well, into the nearest QWindow of the
new QWidget parent.
However we would only do this for the reparented widget itself,
and not any of its child widgets. In the case where the widget
has native children with their own QWindows, the widget itself
may not (yet) be native, e.g. if it hasn't been shown yet, or
if the user has set Qt::WA_DontCreateNativeAncestors.
In these scenarios, we would be left with dangling QWindows,
still hanging off their original QWindow parents, which
would eventually lead to crashes.
We now reparent both the QWindow of the reparented widget (as
long as it's not about to be destroyed), and any QQWindow
children we can reach. For each child hierarchy we can stop
once we reach a QWindow, as the QWindow children of that
window will follow along once we reparent the QWindow.
QWindowContainer widgets don't usually have their own
windowHandle(), but still manage a QWindow inside their
parent widget hierarchy. These will not be reparented
during QWidgetPrivate::setParent_sys(), but instead
do their own reparenting later in QWidget::setParent
via QWindowContainer::parentWasChanged(). The only
exception to this is when the top level is about to
be destroyed, in which case we let the window container
know during QWidgetPrivate::setParent_sys().
Finally, although there should not be any leftover
QWindows in the reparented widget once we have done
the QWidgetWindow and QWindowContainer reparenting,
we still do a pass over any remaining QWindows and
reparent those too, since the original code included
this as a possibility.
We could make further improvements in this areas, such
as moving the QWindowContainer::parentWasChanged() call,
but the goal was to keep this change as minimal as possible
so we can back-port it.

Previously, querying Qt::ImEnabled only returned the value of
isEnabling(), which is incorrect for edit widgets with read-only
properties set, as Qt::ImEnabled indicates whether text can be *input*
through the input method, which results in the IM being able to insert
text into read-only edit widgets.
The fixed version uses both isEnabling() and isReadOnly() values to
determine whether input methods need to be enabled. For some platforms
(like iOS and Android) that rely on IM to select text, a check for
ImReadOnly has been added to their QPA plugins to enable handles on
read-only input boxes.
At the same time, the imEnabledNotImplemented function in the test file
tst_qwidget was modified, since ImEnabling should give a _false_ value
when a lineedit is read-only.

In ccd3bf0871 we introduced code that would
ensure that our call to QWidgetPrivate::setVisible() from QWidgetWindow
would not result in WA_WState_Hidden being set. This code was later
modified in 51300566ff to apply to
widgets that were explicitly shown/hidden.
Unfortunately, the reset of the Hidden and ExplicitShowHide attributes
would in some cases result in the widget having only ExplicitShowHide
after being hidden, which is an invalid state.
It also resulted in the widget having both Visible, Hidden, and
ExplicitShowHide, if first being hidden via QWidget, and then
shown via QWindow, which in turn prevented the widget from being
hidden via QWidget::hide().
As we no longer rely on the adjustments to Hidden/ExplicitShowHide
to fix QTBUG-73021, we can remove the entire logic. Any setVisible
call to QWidgetWindow will either come from outside, in which case
we should respect that and set Visible/Hidden via QWidgetPrivate,
or the setVisible call is a result of QWidget itself (or its parent)
showing the QWidgetWindow, in which case the QWidget visible state
is already up to date and we skip the QWidgetPrivate::setVisible
call.

When destroying a widget via QWidget::destroy(), we clear WA_WState_Created,
and then delete the QWidgetWindow, which in turn hides the widget. But
QWidgetPrivate::setVisible(false) skips hide_helper() if the widget has
not been created, which leaves out important events such as the hide
event, and even more important, fails to clear WA_WState_Visible. As
a result, the widget is left visible (and mapped), even if it has been
destroyed.
This is normally not a big issue for the main use of destroy(), namely
destructing the widget, but for cases where destroy() and create() is
used to recreate the widget this is important.
We now unconditionally call hide_helper() if the widget is not already
hidden. As a result, the widget will correctly be visible=false after a
destroy(). This in turn means we need to re-apply the visible state after
recreating the widget when we detect a mismatch in RHI configuration.
Due to our meddling of the Hidden and ExplicitShowHide attributes in
QWidgetWindow private, a QWidet::show() will not have any effect after
being destroy(). This is okey for now, as destroy() is internal to
a widget, and we make sure to either update WA_WState_Visible and
WA_WState_Hidden (in QWidgetPrivate::setParent_sys), or use the
QWidgetPrivate::setVisible() code path directly, which doesn't
have that issue. The root problem will be fixed in a follow up.

As a result of using QWidget::setVisible to show the child widgets we
would end up also setting ExplicitShowHide. This is not in line with
the intent of ExplicitShowHide, which is to flag a widget as explicitly
shown/hidden by the developer, which in turn prevents Qt Widgets from
toggling WState_Hidden when the widget is reparented.
By using QWidgetPrivate::setVisible instead, we can show the child
without setting ExplicitShowHide.
As side effect of this is that we no longer reset WA_WState_Hidden
from QWidgetWindowPrivate::setVisible(). This is an issue when the
setVisible call comes as a result of destroying the QWidgetWindow,
as that is an implicit hide, and should not result in the widget
having WA_WState_Hidden. QWidget handles this case in hideChildren
by not calling QWidgetPrivate::setVisible -- instead doing its own
reset of WA_WState_Visible. We don't want to untangle this just yet,
so as a workaround we detect that the widget is already !isVisible(),
thanks to hideChildren having hidden it, and then skip the call
to QWidgetPrivate::setVisible that results from QWindow::destroy().

Durin QWidget::destroy() we end up in QWindow::destroy(), which calls

- the widget's title bar and resize handles could be inaccessible
This patch refactors and documents checkRestoredGeometry.
In a first step, the restored geometry's size is checked against
a given screen size. It is corrected if necessary.
In a second step, the restored geometry is moved inside the screen,
if necessary.
It makes the function a static member of QWidgetPrivate in order to
expose it for auto testing and adds a respective test function to
tst_QWidget.
