This CL updates VcnManagementService to notify VcnStatusCallbacks when
the VCN for their specified subscription group enters Safemode. In order
to be notified, the registering app must also have permissions for the
specified permission.

This CL defines VcnStatusCallbacks, which are callbacks used to register
for status updates to a specific subscription group. These Callbacks may
be registered with VcnManager at any time, but will only be invoked for
the specifies subscription group and only if the registering app has
carrier privileges for that subscription.

This CL updates VcnGatewayConnection to use WakeupMessages to support
Safemode detection. Safemode is entered if the VcnGatewayConnection
instance takes more than SAFEMODE_TIMEOUT_SECONDS seconds to a) go from
DisconnectedState to ConnectedState, or b) exit and re-enter
ConnectedState. If this timeout is exceeded, the instance will notify
its managing Vcn via VcnGatewayStatusCallback#onEnteredSafemode.

This change removes the NOT_RESTRICTED capability for Carrier Wifi. This
is done even if a VCN is in safe mode, but will ONLY be performed if the
VCN is provisioned, and has the appropriate carrier privileges to run.
This change also fixes a test bug where the NOT_VCN_MANAGED capability
was not present in the query to getUnderlyingNetworkPolicy(), and
therefore was incorrectly passing.

instances. Specifically, VcnGatewayConnections will notify their Vcn
instance when they enter Safemode. Vcn instances will in-turn notify
VcnManagementService, which notifies all registered

This CL implements #getUnderlyingNetworkPolicy() for

NetworkCapabilities and checks for a corresponding VCN. If one exists,
a VcnUnderlyingNetworkPolicy will be returned with a copy of the
original NetworkCapabilities without the capability NOT_VCN_MANAGED and
with the unwanted capability NOT_VCN_MANAGED.
Any NetworkCapabilities without a corresponding VCN will be returned a
VcnUnderlyingNetworkPolicy with the original NetworkCapabilities intact.

This CL updates UnderlyingNetworkTracker to register NetworkCallbacks.
UnderlyingNetworkTracker uses two types of NetworkCallbacks:
- bringup requests
- selection requests
Bringup requests ensure that VCN-managed Networks are not reaped.
Separate bringup requests are filed for wifi and cell Networks. One cell
request is filed for each subscription ID (subId) in the VCN's
subscription group.
Selection requests are used to allow ConnectivityService to perform
Network selection for the VCN's selected underlying Network (the Network
that VCN traffic will be routed through).

This change implements the Connecting state, where the gateway
connection will be established. In the event of a network switch during
connection, the existing connection attempt will be aborted and
restarted on the new network in an attempt to avoid the case where the
old network is completely lost (eg wifi to cell switch), and IKE stalls
for the entire retry period.
