Walk the tree using the extended-length form of the path (\\?\...), which is not limited by MAX_PATH.
Paths of nested files and directories passed to onexc and onerror and set in exceptions are now extended-length paths, so the error handler can use them (for example to call os.chmod()). The top directory is still reported with the original path.
tempfile.TemporaryDirectory and test.support.os_helper.rmtree() are updated to work with extended-length paths.
Tested on Windows 11 with LongPathsEnabled=0.

tempfile.TemporaryDirectory and test.support.os_helper.rmtree() are
updated to work with them.
