ConnectivityManager: Provide API's to include location sensitive info

Existing NetworkCallback users will get NetworkCapabilities with
location sensitive data removed (except for ownerUid which will be
added for existing apps for backwards compatibility). Apps
have to opt-in to receive location sensitive data.

Note: This was chosen because WifiInfo is the only TransportInfo tha
has location sensitive info & that was added only in Android 12. If we
choose to default to true, all existings apps retrieving
NetworkCapabilities for wifi networks will be blamed for location access
unnecessarily.

Changes:
i) Add a flag in NetworkCallback creation to retrieve
NetworkCapabilities with location sensitive info in their callback.
(More flags are being planned for NetworkCallback for throttling
callback frequency, etc)
ii) For NetworkCapabilities.getOwnerUid(), we will continue to send the
data for apps targeting older SDK (since this is an existing field and
the new flag defaults location sensitive data to off).
