[libcxx-commits] [libcxx] [libcxx] Remove unused Python imports (PR #73724)

[Stephan T. Lavavej via libcxx-commits]

https://github.com/StephanTLavavej created https://github.com/llvm/llvm-project/pull/73724

VSCode's Pylance extension informed me, and text searching confirmed, that these imports are unused. I believe we should be able to remove them harmlessly.
