wifi: iwlwifi: tests: check listed PCI IDs have configs

Add a test that checks, for the old pre-CNVI devices, that
PCI IDs listed in the PCI IDs table will also match in the
config table. Newer ones we test against our database of
devices, but the current database doesn't go back that far,
so at least this checks against the PCI IDs the driver has.
