Sets up an extra drop target on tabs.
This allows to drag arbitrary content onto tabs, for example URLs in a web browser.
If a tab is hovered for a certain period of time while dragging the content, it will be automatically selected.
The [signal@TabBar:AdwTabBar:extra-drag-drop] signal can be used to handle the drop.
