One such tool is SWIG, which happens to support macro expansion, but we have other tools downstream that don't.

We have a bunch of places that run python scripts as part of the build (clang/utils/bundle_resources.py, clang/lib/Tooling/DumpTool/generate_cxx_src_locs.py, compiler-rt/lib/sanitizer_common/scripts/gen_dynamic_list.py, clang-tools-extra/clangd/quality/CompletionModelCodegen.py) – maybe that could work here?

Yeah I agree and that's my fault for suggesting it in the first place to Adrian. We considered Python but weren't sure it was a hard build dependency (even though LLDB relies on it extensively, you can actually turn it off with a CMake flag). If that's the case then that's certainly a viable option.
