PhonePolicy: Gate CONNECT_OTHER_PROFILE per device

* When A2DP or HFP is connected for a device, PhonePolicy will try to
  connect to other profiles such as HFP, A2DP and PAN in case the remote
  device did not connect these profiles themselves.
* De-duping this effort by checking if PhonePolicy handler already has
  the CONNECT_OTHER_PROFILES message  works for a single device but
  won't work when multiple devices are connecting at the same time
  from the remote side. Only the first connected device's connection
  request with be honored and other devices' connection request might be
  dropped if the first device's connection request is still in progress
* Therefore, we need to create a HashSet to gate this message per
  BluetoothDevice
