feat(StatusQ.Controls): introduce StatusSwitchTabBar and StatusSwitchTab

This commit adds two new components to the StatusQ.Controls module:

- StatusSwitchTabBar
- StatusSwitchTab

Usage:

```qml
StatusSwitchTabBar {

    StatusSwitchTab {
        text: "Tab 1"
    }

    StatusSwitchTab {
        text: "Tab 2"
    }

    StatusSwitchTab {
        text: "Tab 3"
    }
}
```

Closes #365
