[XY] xyVis and layeredXyVis layers.

[Kuznietsov]

xyVis

• Remove layers. They will be supported at the layeredXyVis.
• Add referenceLineLayers argument, which is accepting dataLayer type.
• And referenceLineLayers argument, which is accepting referenceLineLayer type.
• And referenceLineLayers argument, which is accepting annotationLayer type.
• Add extendedDataLayer expression function, which is supporting optional table argument. If table is not provided, the input should be used.
• Add extendedReferenceLayer expression function, which is supporting optional table argument. If table is not provided, the input should be used.

layeredXyVis

• Add layers argument, which is supporting extendedDataLayer, extendedReferenceLayer and extendedAnnotationLayer expression function types.

Just a note and maybe it worths adding it here. Lens is going to support another layer type, the annotations. The PR is WIP #126456 but good to have it in mind.

@stratoula, updated the issue.

@Kunzetsov Can you elaborate on why we need dataLayer and extendedDataLayer? What about having only dataLayer with on optional argument which is used when provided? It seems like the two types make it harder for a user to choose the right thing.

@flash1293, xyVis, which will be used at Canvas and VisEditors, is accepting dataLayer, referenceLineLayer and annotationLayer input types (without table argument) for dataLayer, referenceLineLayer and annotationLayer arguments. At the same time, layerXyVis, which will be used only at Lens, is accepting extendedDataLayer, extendedReferenceLineLayer and extendedAnnotationLayer, which have optional table argument. So, for xyVis user will not have any options 😃

@Kunzetsov Ah, I see, that makes sense, thanks for explaining.
