Packaging updates and notes for downstreams

• Updated to use Cython 3.1 universally across the build path -- by :user:lysnikolaou.

  Related issues and pull requests on GitHub:
  #117.

• Made Cython line tracing opt-in via the with-cython-tracing build config setting -- by :user:bdraco.

  Previously, line tracing was enabled by default in :file:pyproject.toml, which caused build issues for some users and made wheels nearly twice as slow.

  Now line tracing is only enabled when explicitly requested via pip install . --config-setting=with-cython-tracing=true or by setting the PROPCACHE_CYTHON_TRACING environment variable.
