[llvm][clang] Remove handling of Python2 ConfigParser module name

[DavidSpickett]

LLVM now requires Python >= 3.8, and ConfigParser was renamed to configparser in 3.0:
https://docs.python.org/3/whatsnew/3.0.html#library-changes

A few places imported it under the Python2 name even for Python3, I have swapped those to the Python3 name.

This was reported by https://pypi.org/project/vermin/ as the file having incompatible versions. Since once import is 2.x and one is 3.x.
