AdapterStatusListener::discoveringChanged: Add meta ScanType and changed ScanType for the changedEnabled value; Expose meta ScanType.

The additional information in the callback is essential in a LE + BREDR environment.
User can also see the current meta ScanType.

ScanType is exposed to Java.

Java's BluetoothAdapter also adds 'ScanType getCurrentScanType()', exposing the last sent meta ScanType.
DBTAdapter.java stores the meta ScanType instead of a boolean flag, hence we can react on LE only scanning for example.

DBTAdapter can call all discovery callbacks for all ScanTypes now.
