wireprotov2: add bookmarks to "changesetdata" command

Like we did for phases, we want to emit bookmarks data attached
to each changeset.

The approach here is very similar to phases: we emit bookmarks
data inline with requested revision data. But we emit
records for nodes that weren't requested as well so consumers have
access to the full set of defined bookmarks.
