The condition for deleting IPv4 forwarding rules.

rules.
2. When the upstream has gone, deletes all rules.
3. When the upstream has changed, deletes all rules.
Test: atest TetheringCoverageTests and check IPv4 offload rules
via dumpsys tethering in the following test cases.
Bug: 190783768
Test cases:
a. Loss upstream interface while tethering
1. Enable WIFI tethering
2. Disable upstream interface
3. Check the rules are removed.
b. Loss downstream interfaces while tethering
1. Enable WIFI tethering
2. Enable BT tethering
3. Disable BT tethering
4. Check the BT tether rules are removed.
5. Disable WIFI tethering
6. Check the WIFI tether rules are removed.
c. Switch upstream interface while tethering
1. Enable WIFI tethering
2. Enable BT tethering
3. Switch upstream interface from cellular to wifi.
4. Check all rules are removed.
d. Enable NAT failure (manual)

The stable connectivity shims are updated to now contain S API, so
tethering tests that assumed that compatibility R behavior was used need
to be updated.
To avoid such failures Tethering tests should have a test target using
updated shims (TetheringNextTests), but this was not done in S
timeframe.

startTrackDefaultNetwork was allowed to called multiple times
before even though there is no one actually do it. However,
in the TetheringTest#verifyDefaultNetworkRequestFiled, a
manual invocation is used to ensure that function supports
multiple entrance.
But with aosp/1697371, startTrackDefaultNetwork is no longer
allowed to be called multiple times, it would lead to log.wtf
and crash system in eng build.
Since the manual invocation of startTrackDefaultNetwork is not
realistic and no longer valid anymore, remove the invocation
that caused the trouble.

This is supported by:
1. Utilize the new API from both NetworkStatsProvider
and IOffloadControl to send data warning quota to hardware.
And pass the warning reached notification back to NPMS.
2. Disable software solution introduced in R release for

and limit notification to hardware.

This is a no-op change that redirect both V1.0 and V1.1 callback
events to the same handling function. Since the V1.1 callback
is extended from V1.0 callback, we can safely use V1.1
callback for both V1.0 and V1.1 control.
The change also provides interface for subsequent
OffloadController changes to set warning and limit at the
