refactor(lane_departure_checker): improve LaneDepartureChecker initialization and parameter handling

[kyoichi-sugahara]

Description

Refactors LaneDepartureChecker initialization by:

• Removing separate setVehicleInfo and setParam calls
• Introducing a new constructor that takes both parameters and vehicle info at initialization

Simplifies code across multiple files:

• plot_map_case1.cpp and plot_map_case2.cpp
• goal_planner_module.cpp
• start_planner_module.cpp

Improves test organization in test_geometric_pull_out.cpp:

• Extracts planner data setup into a separate method
• Reduces code duplication
• Removes unused member variables and imports
