Update BluetoothDevice#setAlias based on API council feedback: now

accepts null input and returns an int (with error codes).
Update CompanionDeviceManager#canPairWithoutPrompt to take a
UserHandle instead of an int. Adds BluetoothStatusCodes class for all
new Bluetooth error / success codes. Moved OOB and hci disconnect
constants to the new BluetoothStatusCodes class.
