Core/AI: AreaBoundary refactor

- Added an auxiliary function IsInBounds to base CreatureAI
- Changed container to vector. Set had no sense because we're storing new pointers, they have different addresses even if the boundary is the same

(cherry picked from commit 2f99fa09c9bacbad376d7a296c3311f94ec8a552)
