[NUI] Fix height calculation of TextLabelLayout

When the label's HeightSpecification is wrap content,
the result of GetHeightForWidth() is used to calculate the text height.

The previous behavior simply used NaturalSize,
so it could not guarantee the behavior of the case below.

```
var label = new TextLabel
{
    Text = "Something long long text...",
    WidthSpecification = LayoutParamPolicies.WrapContent,
    HeightSpecification = LayoutParamPolicies.WrapContent,
    MaximumSize = new Size(400, 400),
    Padding = new Extents(25, 25, 10, 10),
    MultiLine = true,
};
```
