[issue31303] xml.etree.ElementTree fails to parse a document (regression)

Simpler reproducer:

>>> import xml.etree.ElementTree
>>> xml.etree.ElementTree.XML(b'<key attr="' + b'x'*1023 + b'\xc3\xa0""/>')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/serhiy/py/cpython/Lib/xml/etree/ElementTree.py", line 1315, in XML
    parser.feed(text)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 1023: invalid continuation byte

Seems this is a regression in the Expat library.
