[Feature Request]:Virtualization capability of Tree component

Feature Request Description

Hi

As part of our transition to adopting UI5 Web Components in our product, we've encountered a significant performance issue when rendering trees with a large number of nodes.

We would like to kindly request support for tree virtualization—specifically, rendering only the nodes that are visible within the scroll viewport, similar to how libraries like react-window handle virtualized lists. We’ve observed that this type of optimization is already available for ui5-table, and extending similar support to the ui5-tree component would be highly beneficial.

This limitation is currently a major blocker for our adoption of the UI5 Web Components framework. We would greatly appreciate your consideration of this feature request.

Any alternative suggestions are also greatly appreciated.

Thank you.
