The NetworkStatsService.getUidStats() currently doesn't have any
permission check to make sure unpriviledged apps cannot read the stats
of a different uid. It will protentially have security problem since
apps with ACCESS_NETWORK_STATS permission can directly calling into
NetworkStatsService and bypass the check in TrafficStats. Move the uid
check from TrafficStats to NetworkStatsService to fix the problem.

This method is used in TrafficStats to obtain the snapshot for the
calling UID, so narrow it to only return data for that specific case.
We might be tempted to throw an exception or adjust the method
signature, but apps are using the raw AIDL in the greylist, so we
return them an empty NetworkStats if they ask about other UIDs.

In current design, Rat type change in NSS is only for default
subscription. This is only correct for single sim project.
However, it does not correct for multi-sim scenarios such as
CBRS or DSDS, given that all data usage will be attributed
to the Rat type of default sub.
Thus, add a helper class to monitor subscription change event,
and register/unregister dynamically for Rat type change for
every subscription.
Note that unit test of the helper class will be addressed
in follow-up patch.
