net/wifi-firmware-ath1[012]k-kmod: update firmware files

With the removal of the "USE=kmod" and only building packages with
plain firmware files, our version went backwards.  Updating the
firmware will fix this.  For ath1[012]k we can just do that as we
do not yet ship the drivers officially.

Change to a script shipping with ath10k to extract the firmware files
from WHENCE to get them all.  It is questionable if we really want
to have as many flavors or how to ship them in the end, especially
for ath11k and ath12k.

net/wifi-firmware-*: build framework and license hack cleanup

Cleanup the extra layer of "flavour" that came into the build framework
when flavours were introduced at a time when it was not planned.
Make linters some more happy. [1]

Remove the special license hack to install additional files.
If DISABLE_LICENSES is set we still installed files making builds fail [2].
One would hope to always install the lincese files but simply disable
any checking by the framework.
Introduce a new way using LICENSE_COMB=multi to install the default
license file, the extra WHENCE and any possible extra firmware license
files.  Technically this is an abuse of the system too but at least it
should work and not break non default options.

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.

net/wifi-firmware-*: use metaport for "base" and switch to Makefile.inc

Rename the wifi-firmware-base to wifi-firmware-kmod (similar to
gpu-firmware-mod).  The former was never build so technically it
is no move.  Make the new subdir a metaport including all
wireless firmware.
Move the old Makefile to Makefile.inc and adjust the child ports
accordingly.

This solves two problems: (1) the base port is now buildable and (2)
there is a single port to depend on to add all the needed firmware
files to, e.g., put on a release media.

net/wifi-firmware-*: add framework and firmware for various WiFi chipsets

Add a "base port framework" to fetch (WiFi) firmware and license files
from the linux-firmware.git repository and an accompanying FreeBSD
build kmod framework tarball (for now; we might do without that in
the future).
Add child ports for Realtek rtw88 and rtw89, Mediatek mt76, and
Atheros ath10k and ath11k firmware as a start.

This is a beginning in order to stop bloating src.git and the
installed kernels with lots of MB of firmware files whereas usually
only one vebdor/chipset/flavor is needed.  Before fully switching
more infrastructure needs to be in place but this is the first and
most important step.
