feat(lanelet2_map_validator): add validator to check whether intersection lanelets have valid turn_direction tags

[TaikiYamada4]

Description

This PR adds a validator mapping.intersection.turn_direction_tagging that checks whether lanelets in intersections have turn_direction tags and their values are left, right, or straight.

In short, this PR adds the following implementation.

• New validator mapping.intersection.turn_direction_tagging that detects lanelets that belong to intersections but don't have a valid turn_direction tag.
• A test code for mapping.intersection.turn_direction_tagging.
• A document for mapping.intersection.turn_direction_tagging.
• Added mapping.intersection.turn_direction_tagging to autoware_requirement_set.json

How was this PR tested?

1. Confirmed that colcon test --packages-select autoware_lanelet2_map_validator --event-handlers console_cohesion+ passes.
2. Confirmed that the following command shows no mistakes against several lanelet2 maps I have.

ros2 run autoware_lanelet2_map_validator autoware_lanelet2_map_validator -p mgrs -m <PATH_TO_sample_map.osm> -i <PATH_TO_autoware_requirement_set.json> -o ./
