Add missing parser files to Python 3.13 Linux and macOS builds (#456)

This PR fixes the CPython 3.13 distributions on Linux and macOS builds
to include the additional object files in subdirectories of the `Parser`
directory. Will fix #378 when merged.

Windows builds are unaffected by the bug because the Windows build
script uses a different mechanism to collect the object files.
