As a result of 16023fc77c423a267fcc48894ff942e94cf35b86 we were no longer
calling QWindow::setVisible or setVisibility from the QQuickWindowQmlImpl
overrides, but instead deferred them until applyWindowVisibility().

As a consequence, if the QWindow::Visibility of the QQuickWindowQmlImpl
was left at AutomaticVisibility, we would always apply the window state
when making the window visible or hidden, which is a major regression.

We should only apply the window state on first show, if the window's
visibility is AutomaticVisibility, or on explicit requests to set the
window's visibility.

This means a window with visibility: Window.Maximized will initially
show as maximized, but if the user then resizes the window and then
hides and shows it again, the window will show in the normal window
state, instead of re-applying the Window.Maximized visibility, which
matches the pre-6.7.0 behavior.

This also fixes a crash in this peculiar condition:

Item {
    width: 0
    height: 0
    RowLayout {
        anchors.fill: parent
        anchors.leftMargin: 1
        anchors.leftMargin: 1
    }
}

Reason for crash:
As a consequence the layout was rearranged with size == (-1, -1), (which
happens to be the value of uninitialized QSizeF).

This invalid size was passed down to QGridLayoutEngine::setGeometries()
(in the contentsGeometry QRect), and again to ensureGeometries().
ensureGeometries() would return early because of the condition

    if (q_cachedSize == size)

(q_cachedSize is an uninitialized QSizeF by default, and size == (-1, -1)

This caused the q_xx, q_yy, q_widths, and q_height to not be properly
initialized, and it would crash inside
QGridLayoutEngine::setGeometries() when accessing the list:

    qreal x = q_xx.at(item->firstColumn());

The process for exposing a C++ type as an attached type in QML is
explained in the link at the top of the detailed description, but it
could be missed, in which case the list below it would be missing
important information.
