changelogv2: introduce a "changelogv2" feature

Right now, this means using revlogv2, but only for the changelog. We will have

Differential Revision: https://phab.mercurial-scm.org/D10660

# Experimental TODOs:
#
# * Same as for evlogv2 (but for the reduction of the number of files)
# * drop the storage of the base
# * Improvement to investigate
#   - storing .hgtags fnode
#   - storing `rank` of changesets
#   - storing branch related identifier
