[4/n] [sync-switch] replace db-model builder inputs with domain types

[sunshowers]

Follow a pattern similar to the reconfigurator. This allows nexus-switch-config to drop the dependency on nexus-db-model and nexus-db-queries.

Also add a test for a non-BGP port.

Depends on:

• [1/n] [sync-switch] build bootstore bgp peers from already-loaded port settings #10642
• [2/n] [sync-switch] move bootstore config building into nexus-switch-config #10643
• [3/n] [sync-switch] move bfd and address lot reads back to bg task, make the builder pure #10644
