I'd rather fix the clang-tidy integration. I'm quite sure we have ODR violations since we use clang-tidy 18 with clang 17 libraries. These violations break the modules, but other clang-tidy checks may also have issues. Changing https://github.com/llvm/llvm-project/blob/release/18.x/libcxx/test/tools/clang_tidy_checks/CMakeLists.txt#L8 to 18.1 likely fixes the issue.

I forgot about the release branch when I fixed this in main.
