restore: make pathspec mandatory

"git restore" without arguments does not make much sense when it's about restoring files (what files now?). We could default to either git restore . or git restore :/ Neither is intuitive. Make the user always give pathspec, force the user to think the scope of restore they want because this is a destructive operation. "git restore -p" without pathspec is an exception to this because it really is a separate mode. It will be treated as running patch mode on the whole worktree.
