feat: Add HurtBoxOwnerGuard to prevent multiple damage registrations from the same HitBox activation

- Implemented HurtBoxOwnerGuard to ensure that multiple HurtBoxes on the same character do not register damage multiple times during a single HitBox activation.
- Added custom editor for HitBox to facilitate the creation of shape colliders with HitBoxColliderProxy.
- Introduced PhysicsPerceptionSystem for enemy perception, supporting multiple detection modes including RangeCircle, BatchLOS, FanCast, and BoxCast.
- Created EnemyPatrolZone to define patrol and chase areas for enemies, allowing for shared zones among multiple enemies.
- Added BD_IsOutsideZone conditional task for Behavior Designer to check if an enemy or player is outside a defined patrol zone.
