cxxrtl: don't mark buffered internal wires as UNUSED for debug.
Public wires may alias buffered internal wires, so keep BUFFERED wires in debug information even if they are private. Debug items are only created for public wires, so this does not otherwise affect how debug information is emitted. Fixes #2540. Fixes #2841.
