[clang] [llvm] [llvm][clang] Remove handling of Python2 ConfigParser module name (PR #163727)

[David Spickett via cfe-commits]

https://github.com/DavidSpickett created https://github.com/llvm/llvm-project/pull/163727

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.
