    c++: Use better module partition naming
    
    It turns out that 'implementation partition' is not a term used in the
    std, and is confusing to users.  Let's use the better term 'internal
    partition'.  While there, adjust header unit naming.
    
            gcc/cp/
            * module.cc (module_state::write_readme): Use less confusing
            importable unit names.
