[nexus] migrate test_ping_lla_src.py to nexus (#12990)
This commit migrates the test_ping_lla_src.py script from thread-cert to the Nexus test framework. The new test_ping_lla_src.cpp implements the same test logic: - Forms a network with a Leader and two Routers. - Verifies that pings using a Link-Local Address (LLA) as the source succeed when sent to a neighbor's Mesh-Local EID (ML-EID). - Verifies that pings using an LLA source fail when sent to a non-neighbor's ML-EID, as LLAs are only valid for single-hop communication. - Verifies that external routes are not used for LLA-sourced packets. To support this migration, the Nexus Core class was enhanced with: - Overloads for SendAndVerifyEchoRequest that allow specifying a source address. - New SendAndVerifyNoEchoResponse methods to verify that no echo response is received (useful for negative test scenarios). Changes: - Added tests/nexus/test_ping_lla_src.cpp - Updated tests/nexus/CMakeLists.txt to include the new test. - Enhanced tests/nexus/platform/nexus_core.hpp/cpp with new helpers. - Removed tests/scripts/thread-cert/test_ping_lla_src.py.
