Implement wrappers around the Architecture ID types

[rbran]

Instead of using naked ids (u32) for types like: Register, Flag, Intrinsic, etc. This PR replaces those types with wrappers like: RegisterId, FlagId, IntrinsicId, etc.

The objective is to provide a more clear API for the user, once the type RegisterId can't be confused with any other u32.

This pattern also allow the creation of the ArchitectureExt::get_field that can receive any kind of id an return the corresponding type, eg:

let reg_id = get_reg_id();
let flag_id = get_flag_id();
let instrinsic_id = get_intrinsic_id();
let reg: CoreRegister = arch.get_field(reg_id).unwrap();
let flag: CoreFlag = arch.get_field(flag_id).unwrap();
let intrinsic: CoreIntrinsic = arch.get_field(instrinsic_id).unwrap();

id().into()?

[rbran]

Maybe, but not using Into. Maybe something like reg.id().into_inner() or reg.raw_id().

[rbran]

The as i64 can be replaced with .into(). But the .0 can only be replaced with a appropriated named function.

However I didn't add that field helper, I find that a little useless, maybe I misunderstand the purpose but it seems unnecessary. Please correct me if I'm wrong.

Do you mean the ArchitectureFromId::into_value? It was mostly to allow the creation of the function Architecture::field, that allow the user to get any kind of field using a single function.
