It can come from the grammar repo (which is the base for Rust and Swift) or it can be something we write ourselves (what I did originally for C++ in my prototype). For now I don't plan to pursue the latter so the idea would be that this always come from the vendored grammar. I now use CMake to do this for us based on the original `.scm` file (see https://github.com/llvm/llvm-project/pull/181297)
