net/wifi-firmware-*kmod: improve build logic, add flavors, update fw version

- update framework to no longer depend on local distfiles for firmware(9)
  but generate the Makefile hierarchy in post-extract.  Keep a
  Makefile.inc.in in files for simplicity.
- update extracting WHENCE parts using a local WHENCE.awk.in in files
  and a pattern to match the section(s).
- use the already prepared FWSUBS sections for flavors and add the
  FWDRV as "default".  Generate the CONFLICTS_INSTALL conflict and
  PKGNAMESUFFIX entries.  Adjust paths and logic for flavors.
  Depend on the flavors rather the combined ("default flavor") packages
  by default if someone installs wifi-firmware-kmod.
  The wifi-firmware-${name}-kmod packages are still built for older
  versions of fwget shipping in releases.
- add support for iwlwifi and ath12k firmware
- update firmware to linux-firmware.git tag: 20240513 for all drivers.
