UCP/WIREUP: Support EP reconfiguration for non-reused p2p scenarios

[shasson5]

What

Support partial EP reconfiguration: only non-reused, fully wired-up scenarios. (Lanes must not be reused and must all be p2p).

Why ?

PR 2 for EP reconfiguration.

How ?

Add a new function for replacing wireup lane by moving internal AUX EP to the new lane. The following steps are performed:

1. Set uct_ep to be used for new lane: a) for CM flow -> use CM EP. b) otherwise -> create a new wireup_ep.
2. Move aux ep from old config to new wireup lane.
3. Delete old wireup lane.
4. Select lane to be used as new wireup lane: a) for CM flow -> use CM lane. b) otherwise -> select a random lane. (Will be modified in next PRs to look for a non-reused lane).
