Add StrongTypedef to bn::base#8288

Conversation
Introduce `bn::base::StrongTypedef<T, Tag, Mods...>` that can be used to give a primitive type a distinct identity. The wrapped type is not implicitly convertible to or from its underlying type, but its value be accessed explicitly. The operations available on the new type are opt-in through composable modifiers, such as `Equality`, `Ordered`, `Hashable`, `Arithmetic`, etc.

Introduce
bn::base::StrongTypedef<T, Tag, Mods...>that can be used to give a primitive type a distinct identity. The wrapped type is not implicitly convertible to or from its underlying type, but its value be accessed explicitly.The operations available on the new type are opt-in through composable modifiers, such as
Equality,Ordered,Hashable,Arithmetic, etc.The intent is that over time we will move to using strong typedefs to represent instruction indexes, expression indexes, virtual addresses, etc., to prevent unintentionally using values of those types in the wrong contexts.
