AP_DDS: Added attitude target topic
This adds attitude target topic, /ap/experimental/target_attitude. https://github.com/ArduPilot/ardupilot/pull/29850 & https://github.com/ArduPilot/Micro-XRCE-DDS-Gen/pull/5 needs to be merged first
Before merging this, we need to get upstream changes merged. I'd like the API-changing stuff to go in as a separate PR rather than bundling that with a new feature. Overall, this looks good otherwise. It will need some docs and tests to show how it works and ensure it doesn't break.
Alright @Ryanf55 ! I'll add some tests and probably put up a new PR for the API related changes. Upstream and that API changes will be required for this attitude target to be merge
@snktshrma do you plan to get this merged?
@snktshrma Hi, thanks so much for your PR and may I ask if you could allow me to push to your PR?
