rust-revlog: bare minimal NodeTree exposition
The independent `NodeTree` instances needs to be associated to an
index (for forward-checks of candidates) but do not need to
encompass all revisions from that index.
This is exactly how it is used in `scmutil.shortesthenodeidprefix`
and we restrict the implementation to the bare minimum needed there
and to write convincing tests.
It would of course be fairly trivial to add more.
