  worktree: implement `git_worktree_open_from_repository`
  
  While we already provide functionality to look up a worktree from a
  repository, we cannot do so the other way round. That is given a
  repository, we want to look up its worktree if it actually exists.
  Getting the worktree of a repository is useful when we want to get
  certain meta information like the parent's location, getting the locked
  status, etc.
