[Bluetooth]AdapterStatusListener: Renamed; Using a list instead of one-shot callback; Mutable callbacks for_each...

[Bluetooth]AdapterStatusListener:
- Renamed BluetoothAdapterStatusListener -> AdapterStatusListener

- Using a list instead of one-shot callback: Allows utilizing information from multiple actors,
  which also allows a more efficient implementation of the tinyb interfaces.

- Mutable callbacks for_each...: BasicAlgos.hpp adds for_each_idx_mtx(..) template algos,
  allowing to perform one UnaryFunction via indices and utilizing mutex lock
  for thread safety. This pattern reduces code complexity, as we need to
  use the visitor model for the listener multiple times.

- Java: DBTDevice's AdapterStatusListener hook performs certain TinyB one-shot callbacks
