[nexus] add DBR-TC-02 test case for multiple BR reachability (#12732)
This commit introduces the 1_3_DBR_TC_2 nexus test case to verify bi-directional reachability between Thread and infrastructure devices in a topology with multiple Border Routers. Key changes: - Implement test_1_3_DBR_TC_2.cpp for step-by-step execution logic. - Implement verify_1_3_DBR_TC_2.py for pcap-based verification. - Enable OPENTHREAD_CONFIG_BORDER_ROUTING_TESTING_API_ENABLE in nexus platform configuration to support prefix manipulation. - Add icmpv6.opt.pio_preferred_lifetime to pktverify layer fields. - Register the new test case in CMakeLists.txt and the default nexus test run script. - Refactor verify_1_3_DBR_TC_1.py and verify_1_3_DBR_TC_2.py to move nested helper functions to the top level for better modularity. - Remove an unnecessary Deinit() call in test_1_3_DBR_TC_1.cpp and its definition in nexus_infra_if.hpp. The test verifies: - Border Router adoption of existing OMR prefixes in the network. - Router Advertisement (RA) behavior on the infrastructure link, including correct RIO options and suppression of non-deprecating PIOs when another BR is present. - Bi-directional reachability between Thread End Devices and Adjacent Infrastructure Link (AIL) hosts during BR transitions. - Automatic election of a new Leader and promotion to Primary BR upon loss of the previous Leader. - Correct derivation of BR ULA prefixes from the Extended PAN ID.
