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).
