Slider handle is now correctly updated on resize (#12550)

Fixed the issue by replacing the legacy ContainerResizedListener
with adding (and removing) an ElementResizeListener to the
LayoutManager.

Notice also that after this change there are no longer
implementations of the deprecated ContainerResizedListener
in the framework codebase.
