T3871: make boot-time interface naming deterministic and hw-id aware

Multi-vendor PCIe NIC systems could lose or rename Ethernet/wireless
interfaces on boot, because naming was decided from a single per-device
udev event before all hardware had a chance to enumerate.

Replace that with one authoritative pass, run once configuration is
available during router startup: wait for configured hardware, apply
every hw-id binding, and name whatever has none yet by PCIe distance
from the root complex and MAC address - the same result every boot.

A node with its hw-id deleted (NIC replacement) or its whole
configuration removed is treated as an ordinary open slot, filled the
same way - recovering its original hardware whenever the interfaces
that vacated slots this boot also show up as candidates.

Boot now reports any interface still unresolved, and the pass is covered
by a new test suite in vyos-build named: make testifname
