[nexus] add test 5.2.1 REED Attach (#12388)
Adds a new Nexus test case for 'REED Attach' (5.2.1) as specified in the test specification.
Summary of changes:
- Implemented Nexus test 5.2.1:
- Added test_5_2_1.cpp: Sets up a Leader, REED_1, and MED_1 (DUT) topology.
Ensures REED_1 upgrades to a Router when the DUT attaches. Verifies
connectivity from the Leader to the DUT via REED_1 using ICMP Echo.
- Added verify_5_2_1.py: PCAP verification script for test 5.2.1,
ensuring MLE Parent Requests, Address Solicit/Responses, and ICMP
Echo Request/Replies are correctly exchanged and forwarded.
- Updated build and execution scripts:
- Modified CMakeLists.txt to build the new 5.2.1 test executable.
- Updated run_nexus_tests.sh to include 5.2.1 in the default test list.
