An adaptive view switcher designed to switch between multiple views
contained in a [class@ViewStack] in a similar fashion to
[class@Gtk.StackSwitcher].

`AdwViewSwitcher` buttons always have an icon and a label. They can be
displayed side by side, or icon on top of the label. This can be controlled
via the [property@ViewSwitcher:policy] property.

`AdwViewSwitcher` is intended to be used in a header bar together with
[class@ViewSwitcherBar] at the bottom of the window, and a [class@Breakpoint]
showing the view switcher bar on narrow sizes, while removing the view
switcher from the header bar, as follows:

```xml
<object class="AdwWindow">
<child>
<object class="AdwBreakpoint">
<condition>max-width: 550sp</condition>
<setter object="switcher_bar" property="reveal">True</setter>
<setter object="header_bar" property="title-widget"/>
</object>
</child>
<property name="content">
<object class="AdwToolbarView">
<child type="top">
<object class="AdwHeaderBar" id="header_bar">
<property name="title-widget">
<object class="AdwViewSwitcher">
<property name="stack">stack</property>
<property name="policy">wide</property>
</object>
</property>
</object>
</child>
<property name="content">
<object class="AdwViewStack" id="stack"/>
</property>
<child type="bottom">
<object class="AdwViewSwitcherBar" id="switcher_bar">
<property name="stack">stack</property>
</object>
</child>
</object>
</property>
</object>
```

It's recommended to set [property@ViewSwitcher:policy] to
`ADW_VIEW_SWITCHER_POLICY_WIDE` in this case.

You may have to adjust the breakpoint condition for your specific pages.

## CSS nodes

`AdwViewSwitcher` has a single CSS node with name `viewswitcher`. It can have
the style classes `.wide` and `.narrow`, matching its policy.

## Accessibility

`AdwViewSwitcher` uses the `GTK_ACCESSIBLE_ROLE_TAB_LIST` role and uses the
`GTK_ACCESSIBLE_ROLE_TAB` for its buttons.
