ada: Remove incorrect bits in Copy_Node documentation

This patch removes a leftover reference to the concept of node extension
and a note about aspect specification that's been incorrect since at
least the latest rework of aspect specification representation.

gcc/ada/ChangeLog:

	* atree.ads (Copy_Node): Fix comment.
