Move capture 2D trigger node to samples

[snw1317]

Summary

• Move the capture_2d_trigger node from zivid_camera into zivid_samples, matching maintainer feedback that this functionality belongs as a sample.
• Keep the executable name as capture_2d_trigger while changing launch files to run it from zivid_samples.
• Preserve the existing auto-capture launch parameters: auto_capture_2d, capture_2d_rate, capture_2d_wait_for_service_timeout_s, and settings_2d_*.
• Sync with upstream master through v3.3.0 and fix invalid launch XML descriptions by escaping <= as <=.

Testing

• xmllint --noout zivid_samples/launch/*.launch
• git diff --check
• Local colcon build --packages-up-to zivid_camera zivid_samples was attempted, but this WSL machine does not have Zivid Core installed, so CMake cannot find ZividConfig.cmake.

Thank you for the contribution @snw1317!

I think this service should rather be put in zivid_samples. I'd be happy to take over the PR to get it merged as a sample.

[snw1317]

Of course!
Makes sense. Sure that works for me.
