Creates the feature flag `enable_ble_v2_async_scanning_advertising` which
enables/disables the use of the async StartScanning, StopScanning,
StartAdvertising, StopAdvertising, etc methods over the soon-to-be deprecated
synchronous versions of those methods. Opted for feature flag over NearbyFlag,
as ChromeOS is the only current consumer and doesn't use Mendel.
Also sets the feature flag to enabled in the ServiceControllerRouter, which
is where ChromeOS sets NC feature flags at startup.
This CL also fully links up the asynchronous Scanning methods. Advertising
will be addressed in a follow up CL.

Adds authentication status to `ConnectionResponseInfo`, which will pass the result of the authentication to clients when the connection is complete. See go/cros-nearby-presence-np-nc-authentication for details. This will be used in follow up CL to communicate the authentication status to clients of RequestConnectionV3().

Adds authentication status to `PendingConnectionInfo`, which will pass the result of the authentication to clients when the connection is complete. See go/cros-nearby-presence-np-nc-authentication for details. This will be used in follow up CL to communicate the authentication status to clients of RequestConnectionV3().

Constructs a Presence frame using BuildSignedMessageAsInitiator() and write to the AuthenticationTransport for authentication. In follow up CL's, authentication protocol will read the message from the remote device and verify it - see go/cros-nearby-presence-np-nc-authentication for details.

Fetch the local credentials and select the correct local credential by verifying the validity of the time. This CL will be followed by
using the selected local credential for authentication. See go/cros-nearby-presence-np-nc-authentication for details.
PiperOrigin-RevId: 603772266
Expose APIs to fetch local credentials from the CredentialManager, which will be used to fetch a local credential to be used for authentication in follow up CL's. See go/cros-nearby-presence-np-nc-authentication for details.
