changegroup: pass clrevtolocalrev to each group

clrevtolocalrev is a per-changegroup group mapping revisions to
aid with shallow clone.

Back when this functionality was implemented in an extension, this
dict was added to the packer instance so monkeypatched functions
could reference it there. Now that this code is part of core, we
can pass the dict to each consumer properly so it doesn't have to
live on the cgpacker instance. This commit does that.

# A simple script for opening merge conflicts in editor
# A loose translation of contrib/editmerge to powershell
# Please make sure that both editmergeps.bat and editmerge.ps1 are available
# via %PATH% and use the following Mercurial settings to enable it
#
# [ui]
# editmergeps
# editmergeps.args=$output
# editmergeps.check=changed
# editmergeps.premerge=keep
