exchange: move disabling of rev-branch-cache bundle part out of narrow

I'm attempting to refactor changegroup code in order to better
support alternate storage backends. The narrow extension is
performing a lot of monkeypatching to this code and it is making
it difficult to reason about how everything works. I'm reasonably
certain I would be unable to abstract storage without requiring
extensive rework of narrow. I believe it is less effort to move
narrow code into core so it can be accounted for when changegroup
code is refactored. So I'll be doing that.

The first part of this is integrating the disabling of the
cache:rev-branch-cache bundle2 part into core. This doesn't seem
like it is related to changegroup, but narrow's modifications to
changegroup are invasive and also require taking its code for
bundle generation and exchange into core in order for the changegroup
code to work.
