feat(position_error_evaluator): add tool for evaluating position error

[Motsu-san]

Description

This PR adds a new RViz plugin tool autoware_position_error_evaluator for evaluating vehicle position errors by measuring deviations from Lanelet2 map lane boundaries and stop lines.

Key Features:

• Interactive Line Measurement: Click-and-drag interface in RViz to measure position errors
• Dual Measurement Types:
  • Stop Line Measurement: X-axis error (longitudinal deviation) from stop lines
  • Lane Boundary Measurement: Y-axis error (lateral deviation) from lane boundaries
• Automatic Data Logging:
  • CSV export with measurement data (x_error, y_error, yaw_error)
  • Trajectory CSV with vehicle pose (x, y, z, yaw)
  • Automatic desktop screenshot capture after each measurement
• Advanced Features:
  • Delete key undo functionality for removing last measurement
  • Real-time visual feedback with colored line indicators
  • Automatic file management with timestamp-based naming

Link to README

How was this PR tested?

• Build Testing: Successfully built with colcon build --packages-select autoware_position_error_evaluator
• Functionality Testing:
  • Interactive measurement functionality verified in RViz environment
  • CSV output generation and file management tested
  • Screenshot capture functionality validated
  • Undo feature (Delete key) tested for measurement rollback

Notes for reviewers

• This tool is designed for offline analysis and debugging purposes
• Requires ImageMagick (import command) for screenshot functionality
• All output files are saved to ~/evaluate_position_error_using_line_tool/ directory
• The tool automatically handles file naming conflicts with sequential numbering
• Comprehensive README documentation is included with usage instructions and troubleshooting

Effects on system behavior

None. This is a standalone RViz plugin tool that:

• Does not affect runtime vehicle behavior
• Only subscribes to existing topics (/map/vector_map, /localization/kinematic_state)
• Does not publish any topics or modify system state
• Operates independently as a measurement and analysis tool
• All functionality is user-initiated through the RViz interface
