TelephonyManager#hasCarrierPrivileges internally uses
SubscriptionManager#canManageSubscription to decide whether to grant
carrier privilege status to an app or not.
SubscriptionManager#canManageSubscription returns true if caller APK's
certificate matches with one of the mNativeAccessRules or
mCarrierConfigAccessRules. This over-grants carrier privilege status
to apps that only has mNativeAccessRules.
Carrier privilege status should
be granted to the caller APK only if it's certificate matches with one
of mCarrierConfigAccessRules.
Replaced SubscriptionManager#canManageSubscription with
PhoneInterfaceManager#hasCarrierConfigAccess which returns true only if
caller APK certificates matches with one of mCarrierConfigAccessRules of
the given subscription.

Fixed leak of cross user data in multiple settings. - Any app is allowed to receive GET_CONTENT intent. Using this, an user puts back in the intent an uri with data of another user. - Telephony service has INTERACT_ACROSS_USER permission. Using this, it reads and shows the deta to the evil user. Fix: When telephony service gets the intent result, it checks if the uri is from the current user or not. Bug: b/256591023 , b/256819787 Test: The malicious behaviour was not being reproduced. Unable to import contact from other users data. Test2: Able to import contact from the primary user or uri with no user id (These settings are not available for secondary users) (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:36e10a6d0d7b9efc543f8004729fa85751f4f70d) Merged-In: I1e3a643f17948153aecc1d0df9ffd9619ad678c1 Change-Id: I1e3a643f17948153aecc1d0df9ffd9619ad678c1
