Message versioning and translation for ROS

[bkueng]

Follow-up to #23850

• adds versioning to the topic name in the uxrce dds client
• adds a translation node that runs under ROS and converts between different versions of a topic (see this document for details)
• adds CI to ensure whenever a versioned topic changes, a new version is added. The required steps are documented in this README. We can also move that to a PX4 docs page.
• adds CI for the ROS translation node

I ended up adding a script that copies the translation node and msg files into a ROS workspace. I tested an approach of directly adding PX4 into a workspace, but ran into too many issues (e.g. msg namespace cannot be customized independently, or that there cannot be multiple subprojects if the toplevel directory already contains a CMakeLists.txt).

Works as advertised, this is awesome 👍🏻

[mrpollo]

i left a few nitpicky comments regarding CI @bkueng, overall great work

[bkueng]

Thanks for all the reviews and tests. This is getting ready.

[sfuhrer]

@mrpollo good to go from your side?
This PR is required to unblock development on PX4 that touches uorb topics, so would be good if we can wrap it up asap.
