Add ipconnectivity.proto to services jar
This patch moves ipconnectivity.proto and companion serialization
classes from /vendor/google/app/ConnectivityMetrics into the framework
services jar.
This will allow to implement a dumpsys interface for IpConnectivity
metrics events defined in android.net.metrics that output metrics as
a serialized proto.
