net/wifi-firmware-kmod: deal with '?' in file names as sha256 broke it

md5 (sha256) as of 70fde0ed6bbbb1f84c440190ba1e5435f8c90e13 in base
started quoting ? as \? which then goes into the distinfo file and
as a result we fail to find that file later using Mk/Scripts/.

Using the dummy=/ option is not as straight forward with a dynamic list
of distfiles as one would wish.
We now build a full matrix of MASTER_SITE x DISTFILES;  that is for
each "DISTFILE" we generate a :group with a full download URL on each
"MASTER_SITE".  That way each file is still possibly downloadable from
each of the various master sites.

The difference now is that the files stored in distfiles no longer
contain the ?h=<tag> extension as we strip that for the distfile having

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.
