worktree: invoke post-checkout hook (unless --no-checkout)
git-clone and git-checkout both invoke the post-checkout hook following a successful checkout, yet git-worktree neglects to do so even though it too "checks out" the worktree. Fix this oversight. Implementation note: The newly-created worktree may reference a branch or be detached. In the latter case, a commit lookup is performed, though the result is used only in a boolean sense to (a) determine if the commit actually exists, and (b) assign either the branch name or commit ID to HEAD. Since the post-commit hook needs to know the ID of the checked-out commit, the lookup now needs to be done in all cases, rather than only when detached. Consequently, a new boolean is needed to handle (b) since the lookup result itself can no longer perform that role.
