Jonathan Hui 27d57f9925 [nexus] add MATN-TC-10 test case for BBR dataset distribution (#12697 )

This commit implements the MATN-TC-10 test case in the Nexus
simulation framework to verify that a Secondary BBR correctly
takes over forwarding of outbound multicast transmissions when
the Primary BBR fails, specifically focusing on BBR Dataset
distribution and MLDv2/BMLR registration behavior.

Key implementation details include:
- Implementation of the MATN-TC-10 test scenario in C++ simulating
  a topology with two Border Routers (BR_1 as initial Primary,
  BR_2 as Secondary/DUT), a Router, and a Host.
- Verification that BR_2 takes over as the Primary BBR and Leader
  after BR_1 is stopped.
- Validation of BBR Dataset (PBBR) presence in Network Data.
- Addition of a Python verification script to validate:
  - Multicast ping reachability.
  - Correct BBR Dataset distribution.
  - Outbound multicast registration (BMLR/MLDv2) on the backbone.
- Use of explicit multicast re-subscription in Step 14 to ensure
  observable registration traffic within the simulation window.
- Robust packet filters for BMLR (port 61631) and MLDv2 to handle
  platform-specific dissection variances.
- Inclusion of the full test specification as inline comments in
  both the C++ and Python files.
- Registration of the new test case in tests/nexus/CMakeLists.txt
  and tests/nexus/run_nexus_tests.sh.
