This patch modifies the build backend to dynamically enable Cython line tracing only when explicitly requested via the `with-cython-tracing=true` config setting. Previously, having `linetrace = "True"` in `pyproject.toml` was making our PyPI-published wheels slower. Now, line tracing is opt-in: - Regular builds: `pip install .` (no line tracing) - Tracing builds: `pip install . --config-setting=with-cython-tracing=true` (enables line tracing) When tracing is requested, the build backend automatically adds the `linetrace=True` and `profile=True` Cython directives and sets the appropriate C compiler flags. Resolves ansible#767
