This commit adds a new mechanism to detect when Network Data (local or leader) becomes full. When this happens, a callback function is invoked. This callback function can be set using a newly added OT API. The callback is invoked whenever: - The device is acting as the leader and receives a Network Data registration from a Border Router (BR) that it cannot add to Network Data (running out of space). - The device is acting as a BR and new entries cannot be added to its local Network Data. - The device is acting as a BR and tries to register its local Network Data entries with the leader, but determines that its local entries will not fit. The `OPENTHREAD_CONFIG_BORDER_ROUTER_SIGNAL_NETWORK_DATA_FULL` config controls the new mechanism and its API. It is enabled by default when `OPENTHREAD_CONFIG_BORDER_ROUTING_ENABLE` is enabled. This commit also adds CLI support for the new mechanism and adds a test case to validate its behavior.
