narrow: move requirement constant to core

My short-term goal is to move narrowrepo.narrowmatch() onto localrepo
and this is a necessary step for that.

I put the constant in changegroup.py, unlike REVLOGV2_REQUIREMENT,
which is in localrepo.py, since we'll need to access it from the
changegroup module eventually.
