Logical lanes: add road type

[dmataCap]

Add a description

LogicalLane message was extended to support road type information from OpenDRIVE.

Some questions to ask:
What is this change?

• An additional enum type and the respective message extension.

What does it fix?

• Missing road type information to determine the speed limit and to easily display a road in a navigation system.

Take this checklist as orientation for yourself, if this PR is ready for the Change Control Board:

• My suggestion follows the style and contributors guidelines.
• I have taken care about the message documentation and the fields and enums documentation.
• I have done the DCO signoff.
• My changes generate no errors when passing CI tests.
• I have successfully implemented and tested my fix/feature locally.
• Appropriate reviewer(s) are assigned.

Harmonization WG 2023/03/01: Won't adapt any changes from OpenDrive if there are still changes going on in OpenDrive (see 'Overlapping bike lane with lanes' topic).

Is there anything I can do to help this topic be merged? I need this data for simulation of traffic agents.

OSI CCB 2025.10.30: @tbleher Could you check that the definitions here still match current OpenDRIVE?

Sure 😃

I checked with OpenDRIVE 1.8.1 (the currently released OpenDRIVE version), and the enum matches OpenDRIVE exactly (except that OSI has a ROAD_TYPE_OTHER, that OpenDRIVE doesn't have, but my understanding is that all OSI enums have a ..._OTHER value, and ..._OTHER does not have to be in OpenDRIVE).

I'm part of the OpenDRIVE CCB, and so far we have not received requests to add new road types or modify existing types. I do not also see any active Pull Request adding or changing the roadType.
