Replace the hardcoded mapping in `create_pointer_conversion_wrappers` with a Python module loaded at runtime. Add `tools/maint/gen_native_sig_info.py` to regenerate this module by comparing wasm32 and wasm64 builds to detect pointer arguments. Signature changes/corrections: - `_emscripten_proxy_poll_finish`: Removed (dead code). - `setThrew`: Corrected from `_p` to `_p_` (has 2 arguments in C). - `_wasmfs_get_cwd`: Corrected from `p_` to `p` (has 0 arguments in C). - Void returns: Inconsistent `vp` signatures (e.g. `emscripten_builtin_free`, `stbi_image_free`) normalized to `_p`.
