WifiService: Use WifiInfo for masking

Migrate to using the new |parcelSensitiveFields| param for masking
location data in WifiInfo. This will ensure that we have a consistent
mechanism for masking in the legacy and new API's for retrieving
WifiInfo.

Note: This change is not dependent on the device SDK (even though the
change is in an API class - WifiInfo).
