Fix the implementation of BluetoothCodecStatus.equals()
Previously, the BluetoothCodecStatus.equals() implementation
was incorrect when comparing arrays of capabilities.
In the new implementation, the arrays are compared correctly,
and also the ordering of the capabilities in each array is ignored.
Also, added unit tests for class BluetoothCodecConfig and class
BluetoothCodecStatus.
