D6884: bookmarks: remove changectx() method from bmstore (API)

REVISION SUMMARY
  All the callsites of this method have access to the repo, and I'd
  rather not have to duplicate this across alternative bmstore
  implementations. Besides, it feels like a bit of a layering violation.
  
  .. api::
  
    `mercurial.bookmarks.bmstore` no longer has a convenience method
    for looking up changectx instances from a bookmark name. Use
    `repo[repo.bookmarks[name]]` intead of
    `repo.bookmarks.changectx(name)`.
