fix(lanelet2_utils): add invalid bound size handler in combine_lanelets_shape

[sarun-hub]

Description

combine_lanelets_shape is ported from autoware_lanelet2_extension/utilities to autoware_lanelet2_utils in #842.
At that PR, we assumed that the lanelet Bound and centerline will contain at least 2 points as definition, thus, we access the optional value that create lanelet and linestring without less than 1 point handler.

But in some cases, there is only one point in bound, that cause the error in the system. (https://evaluation.tier4.jp/evaluation/reports/567aefe2-5399-5033-926f-087787e3501a/tests/7f7a4f81-66bc-51ba-89ac-18e24310a694/ff7bfb3b-5b56-5564-9763-dcea5f51b4e3/eedc4fbf-71db-5cdd-aa12-f4e6f8a32d26?failure_cause_labels=ConditionFailure%3ASimulationTimeCondition%2CConditionFailure%3AStandStillCondition%2CROSProcessDied%2CSimulationFailure&project_id=autoware_dev)
This PR adds the handler for that case (invalid bound size handler).
