make UNO enums scoped for internal LO code

this modifies codemaker so that, for an UNO enum, we generate code
that effectively looks like:

   #ifdef LIBO_INTERNAL_ONLY && HAVE_CX11_CONSTEXPR
       enum class XXX {
           ONE = 1
       };
       constexpr auto ONE = XXX_ONE;
   #else
      ...the old normal way..
   #endif

which means that for LO internal code, the enums are scoped.

The "constexpr auto" trick acts like an alias so we don't have to
use scoped naming everywhere.
