GH-73991: Support preserving metadata in pathlib.Path.copytree() (#121438)

Browse source 
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()`.
