Replace BoundingBox msgs from vision_msgs with internal variants

[Yadunund]

Signed-off-by: Yadunund yadunund@gmail.com

The msg definitions for vision_msgs::BoundingBox3D and vision_msgs::BoundingBox2D have API breaking changes between galactic and humble versions. To continue supporting both ROS 2 versions in RMF, this PR updates the Obstacle msg definition to include an internal BoundingBox msg and not rely on vision_msgs. But the new messages have the same definition as the galactic version of vision_msgs.
