revlog: decouple caching from addrevision callback for addgroup

For changesets, it is useful to cache the content as it will almost
always be processed afterwards. For manifests on the other hand, the
content is often not used directly as there is a fast path for deltas.
Explicitly disable the cache in exchangev2's manifest handling for that
reason.
