Provide template support to customize the dragged element in the TreeView component

To provide template support for customizing the dragged element in the Blazor TreeView component, we need to allow users to define a custom template that dictates the appearance and structure of the node during the drag operation. This customization will enable users to modify the default drag behavior by using HTML, CSS, and data-binding within a template.


TreeView component on the left side and a simple list (ListView) on the right side. Requirement is to perform drag-and-drop functionality, allowing items to move from the left side to the right side. Additionally, don't want to remove the dragged item from the left-side TreeView component.  As well as need to prevent drag-and-drop actions within the same TreeView component and display a 'not allowed' icon for the TreeView component, do not want to prevent this scenario for the target element.
