[nexus] add test 6.1.7 End Device Synchronization (#12495)

Browse Source 
This commit adds a new Nexus test case for 'End Device Synchronization'
(6.1.7) as specified in the test specification.

Summary of changes:
- Implemented Nexus test 6.1.7:
    - Added tests/nexus/test_6_1_7.cpp: Implements the test execution
      for DUT as a Full End Device (FED). The test verifies that the DUT
      automatically sends Link Requests to neighboring routers after
      attaching to the Leader. The test uses direct method calls, sets
      log level to note, and uses AllowList for connectivity.
    - Added tests/nexus/verify_6_1_7.py: PCAP verification script.
      Validates the MLE Child ID Request to the Leader and subsequent
      unicast Link Requests to Router 1, 2, and 3, ensuring they contain
      all required TLVs. Also verifies receipt of Link Accepts from the
      routers.
- Updated build and execution scripts:
    - Modified tests/nexus/CMakeLists.txt to build the new test.
    - Updated tests/nexus/run_nexus_tests.sh to include 6_1_7 in the
      default test list.
