[definitions] Morality and Attitude enums should be exposed to perform bitwise operations with them

[joelalejandro]

Since these enums are implemented as bitwise operators, if we want to do an action based only on a part of the CreatureAlignment, right now we need:

// Do something if the creature is Lawful.
if (
  creature.alignment === CreatureAlignment.LawfulGood 
  || creature.alignment === CreatureAlignment.LawfulNeutral
  || creature.alignment === CreatureAlignment.LawfulEvil
) {
  // ...
}

While we could have a simpler, shorter form:

// Do something if the creature is Lawful.
if (creature.alignment & CreatureAttitude.Lawful) {
  // ...
}

We would need to export the CreatureMorality and CreatureAttitude enumerables in the @xethya/definitions package.
