Supporting Jazzy distribution

[f0reachARR]

In this PR, I will introduce a support for Jazzy distribution. (Iron is not tested but I think it will work)

There are some changes:

• Add repository information for Jazzy, including new package rosidl_core.
  • rosidl_core is newly introduced package in Create package rosidl_core_generators ros2/rosidl_defaults#22
• Changes for CMake functions
  • Use more proper way (checking dependencies version) to use rosidl_get_typesupport_target
  • Add jazzy as CycloneDDS supported distribution.

I tested this PR on my Ubuntu 24.04 + Unity 2022.3.15f1 + ROS 2 Jazzy environment.

I tested this PR on Ubuntu24.04 + ROS 2 Jazzy environment, but I encountered one error with --standalone option.

CMake Error at CMakeLists.txt:294 (message):
  Could not find yaml
Call Stack (most recent call first):
  CMakeLists.txt:395 (get_standalone_dependencies)

So, I changed these points, and it works successfully.

Thank you @LegitYew0108 ! I confirmed yaml-cpp errors on standalone mode, and fixed it.

Thank you for your work, I would like the maintainer to merge this PR.

I've also tested this branch with Ros2ForUnity, and it works with my Jazzy environment (Ubuntu 24.04, ROS 2 Jazzy)

Maybe the line of find_package is needed as @LegitYew0108 mentioned.

Dear Watanabe,

Could you detail how you managed to get it work with your jazzy environment, do you have your own fork of Ros2ForUnity you might share ?

Many thanks !

Here is my version of ros2-for-unity: RobotecAI/ros2-for-unity#125
In addition to these PR, you may need to use this patch for build errors: #69

Have you tried it ? Because in the ros2cs.repos you are not refering to your fork of ros2cs, so if I do pull the repos its doing :
Detected ROS2 jazzy. Getting required repos from 'ros2_jazzy.repos' ./get_repos.sh: line 9: ros2_jazzy.repos: No such file or directory /home/mechaick/ros2unity_ws/ros2-for-unity

Do I only need to change the target of ros2cs.repo to your work ?

Thats what I tried earlier and was facing other issues when importing in linux the standalone compiled one :

dear Watanabe,

Would it be enough to install it directly like the 22.04 installation? Could you give more detail about your experiences?

Kind regards
