Added --distro and --rmw arguments to run_rviz.sh to be able to

[LuisPovedaCano]

Summary

• Replaces the hardcoded osrf/ros:humble-desktop image and rmw_cyclonedds_cpp middleware in the ROS2 RViz example with configurable --distro and --rmw arguments.
• Adds a unified parametrized Dockerfile that builds the correct image for any supported distro/RMW combination
• Supported distros: humble, jazzy
• Supported middlewares: fastdds, cyclonedds

Usage

Default: humble + fastdds

./PythonAPI/examples/ros2/run_rviz.sh

Explicit combination

./PythonAPI/examples/ros2/run_rviz.sh --distro=jazzy --rmw=cyclonedds

Each distro/RMW combination builds and caches a separate image (carla-rviz--), so switching between them doesn't require a rebuild.

Related Issues:
During the testing of the new example I've noticed 3 issues

• CycloneDDS bad performance #9673
• CycloneDDS ROS2 Jazzy Warnings #9674
• RViz2 intermittent segfault on shutdown when using run_rviz.sh #9675

@JesusAnaya have you ever seen any of these?
