[nexus] add test 5.6.5 Network data updates – Router as BR (#12505)

Browse Source 
This commit adds a new Nexus test case for 'Network data updates –
Router as BR' (5.6.5) as specified in the test specification.

The test verifies that the DUT, as Leader, properly updates and
disseminates network data after receiving new information from a
Router acting as a Border Router with three prefix configurations.

Summary of changes:
- Implemented Nexus test 5.6.5:
    - Added tests/nexus/test_5_6_5.cpp: Implements test execution.
      The test forms a network with a Leader (DUT), Router 1 (BR),
      MED 1, and SED 1. It configures Router 1 as a BR with three
      on-mesh prefixes and verifies the Leader disseminates this
      information. The test uses direct method calls, sets log
      level to note, and uses AllowList for connectivity.
    - Added tests/nexus/verify_5_6_5.py: PCAP verification script.
      Validates CoAP Server Data Notification, CoAP Response, MLE
      Data Responses (multicast and unicast), and MLE Child Update
      exchanges, ensuring all required TLVs and prefix information
      are present.
- Updated build and execution scripts:
    - Modified tests/nexus/CMakeLists.txt to build the new test.
    - Updated tests/nexus/run_nexus_tests.sh to include 5_6_5 in
      the default test list.
