fwget: update wireless IDs for rtw88/89, ath1xk, mt76 and add iwlwifi

Update and add (new) PCI IDs for Realtek rtw88/89, Mediatek 7996/7925,
QCA ath1xk, and add Intel iwlwifi IDs.

Rather than using a package per driver add fine(r) grained flavors
even though it is a lot more likely to break in certain cases.

For Intel we need a great level of detail to match PCI IDs so also pass
the full pciconf -l line to into the pci_* files as "$2" to have access
to these.

This lines up with ports commit 80f50c9eb66d.
