Detemplatize cc property nodes
Property nodes used to be instantiation of TreeNode<T> template with different
payload. There is little gain from it (deduplicate 500 bytes of code for 3
times), while made us to type "->data." a few hundred times.
Also this extra level of indirection adds invisible mental overheads.
This CL detemplatizes TreeNode<T> and flatten the payload to the node.
