Add ATT&CK ID property to objects

[seansica]

• Add Zod schema + types for ATT&CK IDs
  • Technique: T####
  • Subtechnique: T####.###
  • Groups: G####
  • Software: S####
  • Mitigation: M####
• Add class property + getter/setter for ATT&CK ID to all classes that extend AttackBaseImpl.

Example:

// type casting for mitigation IDs
const M1042: MitigationAttackId = "M1042";

// attackId directly retrievable from the class instance
export class TechniqueImpl extends AttackBaseImpl {

  private _attackId: TechniqueAttackId = '';
  
  getAttackId(): TechniqueAttackId {
    return this._attackId;
  }
  ...
}
