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.
