worktree add: add --lock option
As explained in the document. This option has an advantage over the command sequence "git worktree add && git worktree lock": there will be no gap that somebody can accidentally "prune" the new worktree (or soon, explicitly "worktree remove" it). "worktree add" does keep a lock on while it's preparing the worktree. If --lock is specified, this lock remains after the worktree is created.
