[SPARK-9085][SQL] Remove LeafNode, UnaryNode, BinaryNode from TreeNode.
This builds on #7433 but also removes LeafNode/UnaryNode. These are
slightly more complicated to remove. I had to change some abstract classes to
traits in order for it to work.

[SPARK-9086][SQL] Remove BinaryNode from TreeNode.
These traits are not super useful, and yet cause problems with toString in
expressions due to the orders they are mixed in.
