Camillo Bruni 8ab75a56a2 [runtime] Rename Builtins::Name to Builtin 1/2 
- Add new Builtin enum
- Move Builtins::Name:kXXX to Builtin::kXXX
- Update existing code

Follow CLs will unify the mix of using int builtin-ids and
Builtins::Name to only use the new Builtin enum and changing it to
an enum class.
