UCP/WIREUP: Introduce connection-based lanes intersection

[shasson5]

What

A new method for lanes intersection is introduced here, using ep_is_connected UCT API.

Why ?

To remove dependency on dst_rsc_index when performing lane intersection. dst_rsc_index is only supported in CM flow, so in order to support EP reconfiguration in non-CM flow (next PRs), we need to replace it with connection-based method. Tests are covered by sockaddr gtests, as it is the only affected module currently. This PR is the first part of the EP reconfiguration feature.
