Add worktree_prune_reason() to allow a caller to discover whether a worktree is prunable and the reason that it is, much like worktree_lock_reason() indicates whether a worktree is locked and the reason for the lock. As with worktree_lock_reason(), retrieve the prunable reason lazily and cache it in the `worktree` structure.
