This change introduces the `DefaultNetworkRematchMetrics`
class to collect and log data about default network reassignments.
The primary motivation is to monitor the behavior of satellite
networks when they act as a default network fallback. This class
records an event whenever a default network request with the
`PREFERENCE_ORDER_SATELLITE_FALLBACK` preference is moved from
one network to another.
For each reassignment, a `DEFAULT_NETWORK_REMATCH` atom is logged
to ConnectivityStatsLog. This atom includes detailed `NetworkDescription`
protos for the old and new networks, capturing their transport
types, capabilities, and metered/validated states. It also logs
the duration the device spent on the previous network.
Sample metrics:

Test interface tracking is already covered by EthernetManagerTest (in
fact, that test relies heavily on this functionality), so it does not
need to be part of EthernetTrackerTest. Additionally, both
isValidTestInterface() and setIncludeTestInterfaces() are trivial
functions that do not improve coverage significantly. Long-term, the
ethernet unit tests should be reimagined as more of a module-wide unit
test, rather than testing individual classes. This will make the tests
much more valuable and could allow testing scenarios that are not
possible in a end-to-end integration test.

The previous implementation used a fixed start timestamp for
querying network usage statistics, initialized based on the
device's boot time. This caused the query window to grow
indefinitely as the device uptime increased, leading to
inefficient queries that fetched and processed a large
ever-expanding amount of historical data.
This change refactors the logic to use a rolling start
timestamp. The `mStartTime` is now updated after each
usage report is generated (in `onLost`). By resetting
the start time to a more recent point (current time
minus one bucket duration), we ensure that subsequent
queries for usage snapshots are performed over a small,
manageable time window.
This optimization prevents fetching excessive data
from the NetworkStatsManager, improving the efficiency
of the metrics collector. Dependencies for time and
duration have also been abstracted for better testability.

The code should also only consider directly-connected routes for

Skip including the subtype PTR query for both announcement and offload
packets. This is necessary because devices like Googlecast have
numerous subtypes. Including these subtypes in the packets can easily
exceed the MTU limit. Furthermore, the Wi-Fi firmware has limited RAM
available for hardware offload, and including subtypes would consume
excessive memory resources needed for the offload code.

Currently, if the value of opt-in meta-data is not a String,
calling Bundle#getString would result in flooding the system
log with Bundle warning log and callstacks, but without
useful information like the package name.
Thus, a manual type check is performed, and the package name
is logged if a mismatch occurs.

As a follow-up to ag/33089478 and ag/33101784, the intent
receiving and dispatching logic was refactored and centralized
within the newly introduced BroadcastReceiveHelper.
However, due to the potential risks associated with this
refactoring, a kill switch is being added specifically for the
PermissionMonitor refactoring. This will allow for reverting
to the previous implementation (potentially involving code
duplication) to mitigate risks if issues arise.
