narrow: remove narrowrevlog
Core now automatically enables ellipsis support on revlogs when
repositories have narrow enabled. So, we no longer need to globally
register the revlog flag as part of activating the narrow extension
and this code can be deleted.
A side effect of this change is that repositories will now raise an
error on encountering an ellipsis flag when the narrow extension is
loaded. Previously, loading the narrow extension on a non-narrow repo
could result in silent usage of the ellipsis flag. This could lead
to undetected bugs. I think the new behavior is more correct.
