refactor(trajectory_follower_node): apply default param to the param file used for test

[kyoichi-sugahara]

Description

• apply default param to the param file used for test
  • changed parameter in lateral_controller_defaults.param.yaml and longitudinal_controller_defaults.param.yaml to allign with the default parameter defined in the autoware_launcher
• delete unused test files
  • test_lateral_controller_node.cpp and test_longitudinal_controller_node.cpp are not used anymore. It seems to have been accidentally left undeleted in this PR.
• add positive longitudinal velocity condition for straight_trajectory test

Tests performed

I confirmed that the test passed using the following command.

colcon test --event-handlers console_cohesion+ --packages-select trajectory_follower_node

Effects on system behavior

Not applicable.
