Jonathan Hui ef3122b496 [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.
