This commit updates the Multi-AIL Detection feature to operate independently of the Border Routing Manager. This fundamental change allows the detector to be enabled/disabled on its own, rather than being tied to the Border Routing Manager's state. This change also moves the Multi-AIL detection API into a separate `openthread/multi_ail_detection.h` header and introduces new APIs to control the detector independently. Corresponding CLI commands are also added. The `test-505-multi-ail-detection.py` is also updated to validate this new independent behavior. In particular that a device that is not enabled to act as a BR can independently run multi-AIL detection and determine whether, if it becomes a BR, it will cause multi-AIL issues.
