feat(Controls): introduce StatusToolTip component

This moves the `StatusToolTip` component into `StatusQ` and applies some of
the changes done by @jrainville in https://github.com/status-im/status-desktop/pull/2447.

Usage:

```
import StatusQ.Controls 0.1

Button {
    text: "Hover me!"
    StatusToolTip {
        visible: parent.hovered
        text: "Top"
        orientation: StatusToolTip.Orientation.Top // default: Top
    }
}
```

Closes #14
