Jonathan Hui 15c728ed21 [nexus] add MATN-TC-20 test case for automatic re-registration (#12708)
This commit implements the MATN-TC-20 test case in the Nexus
simulation framework to verify that a Parent Router handling a
multicast registration on behalf of an MTD re-registers the
multicast address on behalf of its child before the MLR timeout
expires.

Key implementation details include:
- Implementation of the MATN-TC-20 test scenario in C++ simulating
  a topology with a Router (DUT), a MED, and two Border Routers
  (BR_1 as initial Primary BBR, BR_2 as Secondary BBR).
- Addition of a Python verification script to validate MLE Child
  Update Request/Response exchanges and subsequent MLR.req CoAP
  requests from the DUT to the Primary BBR.
- Verification that the DUT automatically re-registers the multicast
  address when the MLR timeout is updated in the BBR Dataset.
- Inclusion of the full test specification as inline comments in
  both the C++ and Python files, following strict formatting rules.
- Registration of the new test case in tests/nexus/CMakeLists.txt
  and tests/nexus/run_nexus_tests.sh.

What is OpenThread?

OpenThread released by Google is... Thread Certified Component

...an open-source implementation of the Thread networking protocol. Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.

...OS and platform agnostic, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.

...a Thread Certified Component, implementing all features defined in the Thread 1.4.0 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.
