Fix(eos_designs): Sort internal objects for consistent output

[ClausHolbechArista]

Change Summary

Sort internal objects for consistent output

Depending on the inventory ordering, the areas where we pass neighbor information might change.
This reveals itself with dynamic inventories, where the order may change from play to play.

Component(s) name

arista.avd.eos_designs>

Proposed changes

• Sort inband management "parents"
• Sort uplink peers
• Sort trunk groups on vlans
• Sort auto-created native-vlans

How to test

Seen in customer project using dynamic inventories.
Also seen with pyavd where the input inventory is sorted differently.

After applying these fixes, the output is consistent even when the inventory order changes.
