refactor(lane_change): move lane change param

[satoshi-ota]

Description

🤖[deprecated] Generated by Copilot at 9cec5ad

This pull request refactors the behavior path planner code to improve the handling of lane change parameters. It introduces a new LaneChangeParameters struct and a lane_change namespace that contain the lane change specific data and logic. It simplifies the function signatures and reduces the code duplication by passing a LaneChangeParameters object instead of a BehaviorPathPlannerParameters object where appropriate. It also updates the test code and the node parameter server to use the new data structures and namespaces.
