    options, '-Wc++[...]-extensions': Remove undefined one-argument 'LangEnabledBy' option properties
    
    A one-argument form of the 'LangEnabledBy' option property isn't defined,
    and effectively appears to be a no-op.  Removing these only changes
    'build-gcc/gcc/optionlist' accordingly, but no other generated files.
    
    Clean-up for commit ee336ecb2a7161bc28f6c5343d97870a8d15e177
    "c++: Add new warning options for C++ language mismatches".
    
            gcc/c-family/
            * c.opt (Wc++11-extensions, Wc++14-extensions, Wc++17-extensions)
            (Wc++20-extensions, Wc++23-extensions): Remove 'LangEnabledBy'
            option properties.
