[p-tree] add possibility to distinguish drop target about primeng HOT 2 OPEN

Finally with my team we have found a workaround to make it work.
We can use the originalEvent.currentTarget object and check if it contains the class p-treenode-dragover. In this case it's inside the node, otherwise it's aside.

if (!event.originalEvent.currentTarget.classList.value.includes('p-treenode-dragover')) -> aside

Of course this is a workaround not even future proof because if you'll change the class name it won't work anymore.
So I hope you'll work on a real solution

Agreed, just a workaround. There appear to have been several unpublished breaking changes with the tree control. We were also using dropIndex. If that was not the official way to distinguish where it was dropped then some sort of documentation stating the way to do it would be appreciated. We do pay for pro support so if I should be filing a case elsewhere please let me know.
