message: move enum-string conversion routines

Move enum conversion routines out of the 'details' namespace
so they are available for library users and consolidate them
in the 'native_types' header.

In order to support future work of template-specialization on
`variant` types, this also added a level of indirection in the
generated specializations for enums so that they are handled
through a struct-with-op pattern.  (Functions cannot be partially
specialized and overloading the template with std::variant support
requires that).
