This change enables the TETHERING_AND_P2P_GO_LOCAL_AGENT feature
on devices running Android 25Q4 or newer, in addition to being
controlled by the existing feature flag.
A new SdkUtil.isAtLeast25Q4() method is introduced to check for
the specific SDK version.

Unifies the `TETHERING_LOCAL_NETWORK_AGENT` and
`WIFIP2PGO_LOCAL_NETWORK_AGENT` legacy feature flags into a
single mainline beta aconfig flag:
`tethering_and_p2p_go_local_network_agent`.
This change simplifies the logic for enabling the `NetworkAgent`
for both standard tethering (global scope) and Wi-Fi P2P Group
Owner mode (local scope). The agent is now enabled for both use
cases when the new flag is on.
The implementation in `IpServer` and associated tests have
been updated to use the new unified flag.

The IPv6 Router Advertisement (RA) MTU is now derived from
the minimum of the interface MTU and the MTUs of all IPv6 routes
on the upstream interface, before being clamped to the 1280-1400 range.
This ensures the advertised MTU respects any smaller
MTUs specified by individual routes.

RaParams is populated with the upstream IPv4 MTU, rather than the IPv6
or route MTU. This change clamps that value between 1280 and 1400. 1280
as it is the minimum IPv6 MTU and 1400 to keep QUIC working. A follow up
change could improve on this by either adding the IPv6 MTU to
LinkProperties, or (possibly better) binding and connecting a UDP socket
to determine the MTU. Note that at that point the MTU in the Tether6Key
should also be fixed.

This refactoring changes how the bluetoothUseRandomAddress flag is
accessed.
PrivateAddressCoordinator is in a library used by multiple mainline
modules(Tethering, NetworkStack, CaptivePortal, WiFi) and cannot
directly read a Tethering mainline beta flag.
To fix this, the flag's value is now passed down through constructors.
An alternative solution would be to split the Java library for each module,
but with this solution, a single utility class cannot be shared.
This commit is a no-op as the passed value is hardcoded to false.

After T, Bluetooth tethering could use a random address. But if we keep
putting the legacy Bluetooth address in the cache, the coordinator will
always assign the legacy address first until it runs into a conflict.
This change in itself does not do anything. Once we have a
trunk-stable namespace for mainline beta, we will add a flag for
this change, and check the flag in PrivateAddressCoordinator.

If the PAN service disconnects before the BT iface is available, the BT
TetheringRequest will be stuck pending and prevent any new BT
startTethering attempts. This may happen if the user turns BT tethering
on and turns off BT without connecting to any device.
Fix this by always removing the pending BT request when the PAN service
disconnects.

The failure is caused by a RA packet read race condition. The test
receives a callback that local-only tethering has started and
immediately begins listening for an RA. However, the system's RA daemon
may not have finished initializing.
The test's packet reader times out waiting for an RA and returns a null
packet. The waitForRouterAdvertisement then uses the null packet
checking for RA, causing NPE. Change modifies waitForRouterAdvertisement
to check if a packet is null before processing it.
