Bluetooth: show multi-device status in Quick Settings

* In Quick Settings, BluetoothTile used BluetoothController to track
  BluetoothAdapter.ACTION_CONNECTION_STATE_CHANGED intent
  that is only fired when 1st device is connecting/connected and last
  device is disconnecting/disconnected. As result, non-first device's
  connecting/connected states and non-last device's
  disconnecting/disconnected states are not tracked properly.
* Instead, CachedBluetoothDevice.getMaxConnectionState() should be used

Bug: 63509289
Test: Connect to multiple devices and disconnect from multiple devices
