RFR: 8092102: Labeled: truncated property [v11]

[Andy Goryachev]

> Adds **Labeled.textTruncated** property which indicates when the text is visually truncated (and the ellipsis string is inserted) in order to fit the available width.
> 
> The new property reacts to changes in the following properties:
> - ellipsisString
> - font
> - height
> - text
> - width
> - wrapText
> 
> I don't think it's worth creating a headful test (headless won't work) due to relative simplicity of the code.
> 
> **Alternative**
> 
> The desired functionality can be just as easily achieved on an application level, by adding a similar property to a subclass.  What is the benefit of adding this functionality to the core?
> 
> UPDATE 2024/03/07: turns out Labeled in a TableView (in a TreeTableView as well) lives by different rules (TableCellSkinBase:152, TreeTableCellSkin:126).  The consequence of this is that the new functionality **cannot** be fully implemented with the public APIs alone.
