evolve: add evolve info to cmdutil.afterresolvedstates

Adding evolve info to cmdutil.afterresolvedstate will improve the ui when we run
into merge conflicts while evolving. Once we resolve all the conflicts using `hg
resolve`, this will show a message saying "continue: hg evolve --continue".
Other extensions like rebase and shelve also use it and it's very helpful.

  $ cat >> $HGRCPATH <<EOF
  > [defaults]
  > amend=-d "0 0"
  > [extensions]
  > hgext.rebase=
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

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