GH-73991: Support preserving metadata in pathlib.Path.copytree()

[barneygale]

Add preserve_metadata keyword-only argument to pathlib.Path.copytree(), defaulting to false. When set to true, we copy timestamps, permissions, extended attributes and flags where available, like shutil.copystat().

No news because copytree() is new in 3.14.

• Issue: Support moving across filesystems in pathlib.Path, as shutil.move() does #73991
