This introduces a general way to use public enums both in the C++ and the (upcoming) C API. For the C++ case, we now use enum classes rather than enums for public enums. This also includes definitions for C API to_string conversions for public enums. C API definitions in cvc5_types.h are only included from the C API, guarded via a macro (thus, for now, not included yet when the header is included).
