Bug description:
The ntpath.splitroot function appears to have changed in Python 3.13 such that it now raises a UnicodeDecodeError when the given pathname is a bytes containing invalid Unicode characters, but only when running on Windows:
Python 3.13.0b4 (tags/v3.13.0b4:567c38b, Jul 18 2024, 10:14:53) [MSC v.1940 64 bit (AMD64)] on win32

>>> import ntpath
>>> ntpath.splitroot(b"foo\x88")
Traceback (most recent call last):
File "<python-input-1>", line 1, in <module>
ntpath.splitroot(b"foo\x88")
~~~~~~~~~~~~~~~~^^^^^^^^^^^^
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x88 in position 3: invalid start byte
The same code works without raising on Windows when using Python 3.12:
Python 3.12.4 (tags/v3.12.4:8e8a4ba, Jun 6 2024, 19:30:16) [MSC v.1940 64 bit (AMD64)] on win32

>>> import ntpath
>>> ntpath.splitroot(b"foo\x88")

The same code also works without raising on Linux when using Python 3.13 or 3.12:
