AdapterProperties: Track connection state change from more profiles

* AdapterProperties should handle ACTION_CONNECTION_STATE_CHANGED intent
  from more profiles
* AdapterProperties sends BluetoothAdapter.ACTION_CONNECTION_STATE_CHANGED
  with STATE_CONNECTING and STATE_CONNECTED when first profile send out
  the same intent, and with STATE_DISCONNECTING and STATE_DISCONNECTED
  when last profile send out the same intent.
* At the same moment, AdapterProperties also update the return value for
  BluetoothAdapter.getConnectionState()
* Currently, we are only tracking HEADSET (HFP), HEADSET_CLIENT (HFP), A2DP,
  A2DP_SINK profiles, other profiles such as PAN, PBAP, HID profiles are
  not tracked properly and their state change could be missed by
  both intent users and BluetoothAdapter.getConnectionState()
* After this CL, the following profiles will be tracked:
  AVRCP_CONTROLLER, A2DP, A2DP_SINK, HEADSET, HEADSET_CLIENT,
  INPUT_HOST, INPUT_DEVICE, MAP, MAP_CLIENT, PAN, PBAP_CLIENT, SAP

Bug: 37546066
