This gets rid of the excessive generic design of `GraphNode` and restores
it to the original design wherein each node is a `PTransform`. I have also
merged the `bytes` of the SDK-specific data and the `Any` that is
SDK-independent data, since as has been pointed out we won't need both.

Inline PTransform to GraphNode, removing generic design
The GraphNode structure was made more generic to allow the Runner API
and Fn API to share the graph data structure while carrying distinct
payloads on nodes and edges. It seems that the Runner API was already
sufficiently flexible for the Fn API to use its existing payload
design.
