This change introduces `SatisfiedByLocalNetworkMetrics` to count the
number of `NetworkRequest`s per UID that can be satisfied by a
local-only network.
The purpose is to gather data on how many applications register callbacks
that would match non-thread local network connectivity.
This data helps in understanding app behavior and can inform
future development of local-only network features particularly
for the backward compatibility of existing NetworkRequests.
- A new class `SatisfiedByLocalNetworkMetrics` handles the counting and
logging logic.
- `ConnectivityService` calls into this class upon `NetworkRequest`
registration.
- Counts are logged to statsd.
Sample dumpsys output:
SatisfiedByLocalNetworkMetrics: {LISTEN={10217=2}}

Previously, the approach for apps to declare themselves
satellite-optimized was problematic. Relying solely on the
<application> tag for opt-in could significantly increase app
size. This was particularly an issue on older devices, where
the duplication of <meta-data> directly under the
<application> tag into each ProviderInfo could drastically
swell its size. A prime example of this negative impact was
crashes on Android 5.0 (API 21) and older devices, where
PackageManager.queryContentProviders would exceed the 1MB
Binder transaction limit due to the bloated ProviderInfo size.
The `isSatelliteDataOptimizedApp` method is updated to iterate
through a package's services if the application-level meta-data
is not found.

There is an argument that the API is @UnsupportedAppUsage since R and
this code only ships to T. In any case, just to be on the safe side, the
code should ignore NCM interfaces which are not part of the regex. (It
already ignores interfaces which are in tethering/server mode today).
This CL also marks a couple of related functions properly as public.
These functions are not @VisibleForTesting; they belong to the public
interface of the class.

Previously, the "avoid bad WiFi" global setting was limited to a single boolean value (0 or 1),
preventing granular control for multiple carriers.
This commit introduces support for carrier-aware "avoid bad WiFi" configurations using a new,
extensible format: "subId1,value1;subId2,value2;...".
This allows different `subId`s (carriers) to have their own specific "avoid bad WiFi" settings.

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.
