This commit allows IKEv2/IPsec VPN to propose more algorithms that
newly added in IpSecAlgorithm. Those new algorithms have stronger
security guarantees and better performances.

This commit also removes algorithm name validation because all
algorithms are URL encoded to ensure no special characters create
problems due to their use by VpnProfile for list or field delimiting
(e.g. rfc7539esp(chacha20,poly1305))

* changes:
  Make VcnTransportInfoTest pass on AOSP.
  Immediately redact VcnTransportInfo.
  Do not automatically redact TransportInfo objects.

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.

Currently, NetworkCapabilities always redacts the TransportInfo
objects it contains whenever a defensive copy is made. This makes
it impossible to make a defensive copy on a TransportInfo
parcelled from another process without redacting it.

Stop redacting by default; instead rely on ConnectivityService
explicitly calling NetworkCapabilities' redacting constructor
when it returns a NetworkCapabilities object to an app via a
callback or synchronous call. This is currently done by
- createWithLocationInfoSanitizedIfNecessaryWhenParceled, which
  is called from callCallbackForRequest, getNetworkCapabilities,
  and getDefaultNetworkCapabilitiesForUser.
- getNetworkCapabilitiesWithoutUids, which is used when sending
  ConnectivityDiagnosticsManager callbacks. In this method,
  unconditionally redact all information, which is what the code
  did previously due to the default redaction setting for empty
  NetworkCapabilities objects being REDACT_ALL.

Move the tests together with packages/Connectivity code, so both can be
moved to packages/modules/Connectivity together.

Also reorganize unit tests in a unit/ directory, as other tests
(integration/, common/ etc.) have been added in tests/net since they
were created. This makes the directory structure consistent.
