Revert^2 "Replace the usage of UidRange"
b6c51b2c978fbcb9c1507b61635c64229c8ffe53
UidRange is used in a shared way between ConnectivityService
and VPN through the use of NetworkCapabilities. UidRange will
be part of the ConnectivityService mainline but Vpn.java will
stay in the framework. We need a way to replace the APIs using
UidRange, or to make UidRange system API. The only really
relevant surface here is NetworkCapabilities#{setUids, getUids}.
The need for UidRange could be replaced by an integer Range, so
replace the usage of UidRange by a integer Range in
NetworkCapabilities#{setUids, getUids} and update the relevant
callers.
