[nexus] add test 5.3.11 Address Query Timeout Intervals (#12430)
Adds a new Nexus test case 5.3.11 to validate 'AQ_TIMEOUT' and 'AQ_RETRY_TIMEOUT' intervals in the Address Query transmission algorithm. The test verifies that the DUT: - Correctly generates Address Query Requests on behalf of its MED child when sending Echo Requests to a non-existent mesh-local address. - Correctly implements the retry delay by NOT initiating a new Address Query frame if a subsequent Echo Request is sent before the 'ADDRESS_QUERY_INITIAL_RETRY_DELAY' expires. - Initiates a new Address Query Request if an Echo Request is sent after the 'ADDRESS_QUERY_INITIAL_RETRY_DELAY' has expired. Summary of changes: - tests/nexus/test_5_3_11.cpp: Implemented test logic using direct method calls and 'AllowList' for topology control. - tests/nexus/verify_5_3_11.py: Added PCAP verification ensuring correct Address Query generation and retry interval logic. - tests/nexus/CMakeLists.txt: Included the new test in the build system. - tests/nexus/run_nexus_tests.sh: Added 5_3_11 to the default nexus test list.
