changegroup: track changelog to manifest revision map explicitly

Previously, self._nextclrevtolocalrev was only populated as part
of the changelog lookup callback. But cgpacker._close() was looking
at self._nextclrevtolocalrev on every invocation.

Since self._nextclrevtolocalrev is for communicating the mapping
of changelog revisions to manifest revisions, this commit refactors
the code to make that explicit.

The changelog state now stores this mapping. And after the changelog
group is emitted, we update self._clrevtolocalrev with that dict.
self._nextclrevtolocalrev is unused and has been deleted.
