[nexus] add test 1.2.LP.5.3.7 for SSED CSL Synchronized Timeout (#12611)
This commit adds a new Nexus test case 1.2.LP.5.3.7 to validate that a Router (DUT) correctly supports a Synchronized Sleepy End Device (SSED) modifying the CSL Synchronized Timeout TLV. Specifically, this test verifies: - Initial CSL synchronization with a 10s timeout. - SSED successfully updating the timeout to 20s via MLE Child Update. - DUT maintaining connectivity beyond the original 10s timeout. - DUT correctly buffering frames when CSL synchronization expires after the timeout is reverted to 10s. - Successful resynchronization and buffered frame delivery. Detailed changes: - tests/nexus/test_1_2_LP_5_3_7.cpp: Implemented the C++ test logic using the Nexus simulation framework. - tests/nexus/verify_1_2_LP_5_3_7.py: Added a Python script to validate the packet traces and ensure protocol compliance. - tests/nexus/CMakeLists.txt: Added the new test to the build system. - tests/nexus/run_nexus_tests.sh: Included the test in the default Nexus test suite.
