The design is very simply expressed :
An offer is needed for a request if and only if that offer
might beat the satisfier for that request.
The implementation of "might beat" is NetworkRanker#mightBeat.

This patch introduces the concept of a network offer that
providers send to Connectivity to register for relevant
requests. This lets them see only requests that they can
hope to satisfy considering their capabilities and score
filters.
This is meant to replace the filtering mechanism currently
implemented by NetworkFactory. The reason for replacing
this mechanism is that the old mechanism does caps and
score filtering on the factory side, which requires these
two filters to be contextless and available system-wide,
including in separate processes from the system server.
These constraints severely limit and complexify in
particular what the score comparisons may look like. In
the past the score comparison was only integer-based,
making the code duplication not much of a problem, but as
this scheme is becoming unsustainable by spreading the
complexity of the selection across the entire stack, a
centralized mechanism is now necessary.
This patch only introduces the new objects and has CS
keep track of them, but does not actually use them yet.
Followup patches will implement the logic of calling
the offer callbacks.

- The method does not cause an actual data stall.
- The detectionMethod parameter refers to
ConnectivityDiagnosticsManager.DataStallReport constants (which
already use an IntDef).

This is similar to onBlockedStatusChanged(Network, boolean) but
it allows the callback holder to know the exact reason why
networking was blocked. It is useful to privileged system
components such as JobScheduler that are able to ignore some
blocked reasons but not others.
Also add a new BLOCKED_REASON_LOCKDOWN_VPN that is used when
networking is blocked because an always-on VPN is in
lockdown mode.
Also move BLOCKED_METERED_REASON_MASK to ConnectivityManager.
This is necessary because ConnectivityService must ensure that
the blocked status callbacks are correctly sent when meteredness
changes (e.g., a UID that is blocked on metered networks will
become unblocked on a network that becomes unmetered). In order
to do this it needs to know which reasons apply only on metered
networks.
