Improve performance of path construction by skipping the addition of the path anchor (`drive + root`) to the internal `_parts` list. This change allows us to simplify the implementations of `joinpath()`, `name`, `parent`, and `parents` a little. The public `parts` tuple is unaffected.

I'm not sure about this change - I don't like how it makes edit: addressed by renaming |

Updated timings: Something like a 10% speedup. |
