[nexus] add test 5.6.9 Router Behavior - External Route (#12518)
This commit adds Nexus test 5.6.9 which verifies that a router properly forwards data packets to a Border Router based on Network Data information. The test implementation includes: - test_5_6_9.cpp: C++ test execution that sets up the topology using Leader, two Routers (one as DUT), a MED, and a SED. It configures external routes and triggers ICMPv6 Echo Requests. - verify_5_6_9.py: Python script to verify the pcap output against the test specification. Key implementation details: - Use direct method calls instead of OpenThread APIs where applicable. - Configure node connectivity using AllowList. - Set log level to 'note'. - Follow specific comment and logging formats as required by the nexus test framework. - Avoid magic numbers by using constants for time and identifiers. - Added 5_6_9 to CMakeLists.txt and run_nexus_tests.sh default list.
