A widget letting you switch between multiple views contained by a
[class@ViewStack] via an [class@ViewSwitcher].

It is designed to be used as the title widget of a [class@HeaderBar], and
will display the window's title when the window is too narrow to fit the view
switcher e.g. on mobile phones, or if there are less than two views.

In order to center the title in narrow windows, the header bar should have
[property@HeaderBar:centering-policy] set to
`ADW_CENTERING_POLICY_STRICT`.

`AdwViewSwitcherTitle` is intended to be used together with
[class@ViewSwitcherBar].

A common use case is to bind the [property@ViewSwitcherBar:reveal] property
to [property@ViewSwitcherTitle:title-visible] to automatically reveal the
view switcher bar when the title label is displayed in place of the view
switcher, as follows:

```xml
<object class="GtkWindow">
<property name="titlebar">
<object class="AdwHeaderBar">
<property name="centering-policy">strict</property>
<property name="title-widget">
<object class="AdwViewSwitcherTitle" id="title">
<property name="stack">stack</property>
</object>
</property>
</object>
</property>
<property name="child">
<object class="GtkBox">
<property name="orientation">vertical</property>
<child>
<object class="AdwViewStack" id="stack"/>
</child>
<child>
<object class="AdwViewSwitcherBar">
<property name="stack">stack</property>
<binding name="reveal">
<lookup name="title-visible">title</lookup>
</binding>
</object>
</child>
</object>
</property>
</object>
```
