Adds control modes to RobotMotionCommand

[barulicm]

This PR updates RobotMotionCommand to support the additional control modes available in the radio packets.

Change summary

• Removes leftover msg/srv files that were previously moved to ssl_ros_bridge
• Adds ateam_msgs/msg/Twist2D to replace geometry_msgs/msg/Twist for data efficiency
• Removes use_world_velocities parameter from Kenobi as we don't actually use it anywhere and it won't be relevant soon.
• Adds body_control_mode field to RobotMotionCommand and fields for control mode parameters
  • pose
  • velocity
  • acceleration
  • limit_vel_linear
  • limit_vel_angular
  • limit_acc_linear
  • limit_acc_angular
• Updates packages that use RobotMotionCommand messages. All existing publishers are still only using BCM_LOCAL_VELOCITY

Note: Simulation radio bridge still only supports local velocity control. Adding support for other modes is future work.
