evolve: unrelated parts of splits are no longer considered content-divergent

Let's backport e68fe567a780 from core that improves content-divergence
computation. This way we can both provide a better experience to evolve
extension users on older Mercurial versions, and don't have to fix evolve tests
for hg 6.1 that we use for one of our CI jobs.

=================================================================
Test automatic unstability resolution for multiple advanced cases
=================================================================

There are dedicated test case for each instability, but this file check some
basic case for each type.

XXX dispatching each these test case in appropriate file would make sense.

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  >   hg log -G --template \
  >     '{rev}:{node|short}@{branch}({phase}) bk:[{bookmarks}] {desc|firstline}\n' "$@"
