WifiStateMachine: Always return a copy of WifiInfo
WifiStateMachine#syncRequestConnectionInfo() should always return a copy
of WifiInfo to prevent external services directly accessing a local
variable in WifiStateMachine. Binder calls within the same process
doesn't parcel objects, hence this is needed to prevent other threads in
system_server directly using a local object within the wifi service.
Bug: 64207440
Test: Unit test that checks for object returned from
WifiStateMachine#getWifiInfo() vs
WifiStateMachine#syncRequestConnectionInfo().
