wifi-service: Link against service-stubs

This is required for resolving the SystemService class which was
recently marked a @SystemApi.

Also,
a) Cleanup the libraries needed in final wifi-service target.
b) Chnage from framework-telephony to framework-telephony-stubs.
c) Changes in WifiService to use formal @SystemApi versions of methods.

Bug: 146145144
Test: Compile wifi-service against system stubs (ag/10081894) &
ensured that SystemService related errors are no longer present.
