Add test for GenericPublisher/Subscriber

[h-suzuki-isp]

Please, refer to ros2/rclcpp#2448.

Because I added tracepoint for GenericPublisher and GenericSubscriber, I add some tests to test_tracetools.
I have added the following tests.

• src/
  • test_generic_ping.cpp
  • test_generic_pong.cpp
• test/
  • test_generic_pub_sub.py
  • test_generic_subscription.py

The Rpr__ros2_tracing__ubuntu_noble_amd64 job failure is expected due to the transition to Ubuntu Noble.

The reason why the ros2_tracing / test (ubuntu-22.04, rolling, source, instr-enabled, tp-included) job fails is because only this PR branch gets built; your rclcpp/rcl/rmw_* branches are not used. I've added a repos file to this PR description so that it runs with your other changes. Can you do git commit --amend --no-edit and then force push so that CI runs again? The tests seem to successfully pass locally for me when I use all the relevant branches.

@christophebedard
Thank you for your help.
As a result of running CI again, the test pass successfully.

It looks good to me, but I'm just trying to run the tests with the other rmw implementations too. For some reason I can't get RMW_IMPLEMENTATION=rmw_connextdds to work.

Oops, I didn't have rti-connext-dds-6.0.1 installed on my system, that's probably why.

Thanks for iterating!

Let's now wait for full CI (under the rclcpp PR) and perhaps some final reviews for the changes to the rmw implementations.

Alright, all other PRs have been merged, so I'll merge this one. See ros2/rclcpp#2448 (comment) for CI.

Thank you for the contribution @h-suzuki-isp!
