wireprotov2: define type to represent pre-encoded object
An upcoming commit will introduce a caching layer to command
serving. This will require the ability to cache pre-encoded data.
This commit introduces a type to represent pre-encoded data and
teaches the output layer to not CBOR encode an instance of that
type.

Now narrow clone this and get a hopefully correct graph

To make updating the tests easier, we print the emitted nodes
sorted. This makes it easier to identify when the same node structure
has been emitted, just in a different order.
$ hg log -T '{if(ellipsis,"...")}{node|short} {p1node|short} {p2node|short} {desc}\n' | sort

But seeing the graph is also nice:
$ hg log -G -T '{if(ellipsis,"...")}{node|short} {desc}\n'
