[XY] xyVis and layeredXyVis. (#128255)

* Added extended layers expressions.

* Added support of tables at layers.

* Added annotations to layeredXyVIs.

* Refactored the implementation to be reusable.

* Fixed undefined layers.

* Fixed empty arrays problems.

* Fixed input translations and removed not used arguments.

* Fixed missing required args error, and added required to arguments.

* Simplified expression configuration.

* Added strict to all the expressions.

* Moved dataLayer to the separate component.

* Refactored dataLayers helpers and xy_chart.

* fillOpacity usage validation is added.

* Fixed valueLabels argument options. Removed not used. Added validation for usage.

* Added validation to the layeredXyVis.

* Fixed extent validation.
