[clang] [libclang/python] Add a few things to the python api (PR #120590)

[Mathias Stearn via cfe-commits]

https://github.com/RedBeard0531 created https://github.com/llvm/llvm-project/pull/120590

I modified a local copy of cindex.py to add these when working on something and wanted to upstream the improvements.
