Description

Currently, we place lanelet2_extension at autowarefoundation/autoware.universe/map/lanelet2_extension

This cause a problem, for example, scenario_simulator_v2 forked this package to avoid complex CI workflows by referencing autoware.universe repository.
It it not the best approach.

Therefore, it is desired to move widely referenced packages to autoware_common.

Purpose

To remove unnecessary duplicates.

Possible approaches

Move lanelet2_extension from autowarefoundation/autoware.universe to autowarefoundation/autoware_core.

Definition of done

• The package is added to autoware_core.
• The package is removed from autoware.universe.
