feat(goal_planner): secure lateral distance for path planning with co…

…rresponding to the centrifugal force (#5196) * add feature to plan the path with considering latral overshoot Signed-off-by: Yuki Takagi <[email protected]> * separate a function in "safety_check" in order to that "goal_planner_module" can handle the ego_polygons Signed-off-by: Yuki Takagi <[email protected]> * add visualization codes fix the handling miss of sign of value Signed-off-by: Yuki Takagi <[email protected]> * refactor codes based on comments in the PR Signed-off-by: Yuki Takagi <[email protected]> --------- Signed-off-by: Yuki Takagi <[email protected]>
