Add a system api to fetch uuids by the specific transport 

The functionality is similar with fetchUuidsWithSdp which uses TRANSPORT_AUTO. Bt stack depends on the devie type and address type to do sdp or gatt service discovery. Add an api to specific the transport. It would be fexible to handle the dual mode device.
